Re: Cr etchant: etching rate?
Thanks for letting us know about the expired Cr-14 etchant -- it should not have been in there and has now been replaced with current stock. The shelf-life is pretty short (3 months) so we need to keep an eye on it.
As for VLSI etchant etch rates, the Berkeley Microlab lab manual has an excellent reference that is linked on the wiki:
http://microlab.berkeley.edu/labmanual/chap1/JMEMSEtchRates2(2003).pdf
Please remember that the etch rates depend on film quality and that can vary depending on the machine and conditions of deposition. So the etch rates in this document should not be taken at full face value, but as a good starting point -- you should always verify etch rates against the actual film you are using in a critical etch. And so, yes, there is a delay in Cr etching because Cr is highly reactive and forms a native oxide on the surface which etches more slowly than bulk Cr.

For the Cr etchant that we have in lab (Cr-14), the etch rate should be ~93nm/min from literature. Note that our Cr etchant is expired (since April 2009), so literature etch rates may not be reliable.
From experience, the etch seems to start only after ~30sec in solution, and the etch rate is quite fast. In about 1 min, I could etch 10nm Cr. It doesn't seem like the etch rate is linear in time and varies greatly (perhaps because it is expired), so it may undercut resist patterns significantly.

e-Workshop: All-Spin Logic
All-Spin Logic
to be presented by Supriyo Datta, Behtash Behin-Aein and Kaushik Roy from the
Purdue University
on Tuesday, March 30th at 1pm. Stanford site for this tele-seminar
will be set up at Allen (CISX) 316X.
Abstract: The possible use of spin rather than charge as a state
variable in devices for processing and storing information has been
widely discussed, because it could allow low-power operation and might
also have applications in quantum computing. However, spin-based
experiments and proposals for logic applications typically use spin
only as an internal variable, the terminal quantities for each
individual logic gate still being charge-based. This requires repeated
spin-to-charge conversion, using extra hardware that offsets any
possible advantage.
We propose a spintronic device that uses spin at every stage of its
operation: information manipulation, transport, storage, input and
output are all accomplished with magnets and spin-coherent channels.
Contrary to the typical spin/magnet based logic schemes, the all-spin
scheme neither relies on ordinary magnetic fields (generated by
current carrying wires) nor does it rely on electrical read-out of
magnetic states. Binary data are represented by the bi-stable states
of nanomagnets (i.e. magnetic polarization) which can be non-volatile.
Application of a voltage signal to a magnetic contact (input data bit)
creates a spin-current in a channel which can be conveniently guided
and routed to another magnetic contact (output data bit) where it
determines its final state based on spin-torque phenomenon.
The all-spin device could potentially find use for low-power digital
logic since it should satisfy the five essential requirements for
logic applications namely nonlinearity, gain, concatenability,
feedback prevention and a complete set of Boolean operations.
Satisfaction of these essential characteristics paves the way for the
design of large scale digital circuits. Cascading and clocking of
logic gates will be discussed along with the
device/circuit/architecture co-optimization of all-spin logic (ASL).
While the focus of the talk will be on digital logic, it is
interesting to note that the all-spin scheme could provide a basis for
unconventional approaches. For example the spin accumulation in a
channel underneath a magnetic contact could provide a 'weighted
average' of different inputs that makes it switch ("fire") when it
exceeds a threshold like neural networks. Alternatively the magnetic
contacts on top of the channel could possibly serve as Input-Output
interface for spin-based quantum computing.

Getting ready for the next Coral release ....
Within the next couple of days, we will be releasing a new version of
Coral that will require use of Java Version 6 instead of Java Version
5. Why? Java 5 has reached its End of Service Life and is less
supportable than the current version (Java Version 6). More
importantly, new Coral capabilities will likely use features that are
available only in newer versions of Java. For example, people have
suggested that we be able to open xReporter from within Coral and have
also suggested that links to online documentation be available from
within Coral. Both of those features will be available in the new
release, but require a feature that is only available in Java 6 ... the
ability to open the default browser from within a Java application.
How can you prepare? If you already have Java 6 on your machine, you
are ready to go and do not have to do anything. If you have Java 5,
however, you will want to download and install the Java 6 runtime
environment. How can you tell? If you are on a Windows machine, you
can open the "Run ..." command line window from the Start Menu and type
in the command:
javaws -viewer
This will open the Java Web Start cache viewer which will open two
windows: one named Java Cache Viewer and the other named Java Control
Panel. When those open, close the Java Cache Viewer and then click the
Java tab on the Java Control Panel. On that panel, there should be a
button named "View" that will show you a list of one or more versions of
Java currently installed on your machine. You may have several, but you
are looking for one that is listed as Platform = 1.6 (which is Java 6).
If you only have Platform = 1.5 entries, then you only have Java 5 and
will need to download and install a Java 6 runtime environment.
If you need to do that go to:
http://java.sun.com/javase/downloads/index.jsp
On that page there are a number of red buttons that say "Download" ...
but there will be only one button that says "Download JRE"
If you click that link, you will be able to download and install the
Java Runtime Enviroment onto your machine. That version will run the
existing version of Remote Coral but will also be what you need when we
release the new version of Java later this week.
Note: if you are on a Linux, Solaris, or Mac OS X platform, you can
easily tell what version of Java you are running by opening a command
line window and issuing the command: 'java -version'.
Let me know if you have any questions,
John

Fuel Cell Science and Technology
Spring 2010
Tuesday, Thursday 4:15pm-5:30pm
Lane History Corner (Bldg 200), Room 305
Audience: Targeted at advanced undergraduate or beginning level graduate students in the engineering or physical sciences. We anticipate diverse student backgrounds and furthermore recognize that the electrochemical concepts will be new to most students. Therefore, the material will be presented assuming no prior background in electrochemistry. Much of the material covered will be theoretical and fundamental in nature.

Description: Fuel cells provide one of the most efficient means for converting the chemical energy stored in a fuel to electrical energy. Fuel cells offer improved energy efficiency and reduced pollution compared to heat engines. While composed of no (or very few) moving parts, a complete fuel cell system amounts to a small chemical plant for the production of power. This course introduces students to the fundamental aspects of fuel cell systems, with emphasis placed on proton exchange membrane (PEM) and solid oxide fuel cells (SOFC). Students will learn the basic principles of electrochemical energy conversion while being exposed to relevant topics in materials science, thermodynamics, and fluid mechanics.
Outline:
Fuel Cell Principles
What is a Fuel Cell?
Fuel Cell Thermodynamics
Fuel Cell Kinetics
Fuel Cell Charge Transport
Diffusion and Mass Transport
Fuel cell Modeling
Fuel cell Characterization
Fuel Cell Technology
Fuel cell Types
Fuel cell Stacking
Fuel cell Systems
Fuel cell Applications
Objectives: By the end of the course, students will have gained the skills and knowledge to demonstrate the following objectives:
· Fuel Cell Characteristics. Contrast the advantages and disadvantages of fuel cells to other energy conversion technologies (e.g. heat engines). Discuss the advantages and disadvantages between the various fuel cell types (SOFC, MCFC, PAFC, AFC, PEMFC).
· Fuel Cell Thermodynamics. Perform thermodynamic calculations to quantitatively predict ideal fuel cell voltages as a function of gas concentrations, pressure, and temperature. Calculate thermodynamic efficiencies. Perform heat and mass balances on fuel cell systems. Describe the basic mechanisms of fuel cell reactions, electron transfer, and ionic transport at the molecular scale.
· Fuel Cell Kinetics. Derive equations for activation, IR, and concentration losses in fuel cell systems. Assemble a complete (simple) analytical model for a fuel cell system and use it to predict fuel cell performance over a range of operating conditions (e.g. at various temperature, pressures, feed rates, etc.) Identify the most significant kinetic constraints that limit current fuel cell performance and suggest research directions to improve performance.
· Fuel Cell Research. Identify the major materials issues remaining in fuel cell design. Describe the most important characterization techniques used to test fuel cell performance and identify bottlenecks.
· Fuel Cell Systems. Describe the major strategies for fuel cell stacking. Compare planar vs. vertical fuel cell interconnection. Discuss the major fuel cell system applications (portable, transportation, stationary power) and be able to argue which fuel cell types are most suited for each application. Discuss and describe the ancillary equipment necessary for a complete fuel cell system (Compressors, humidification, reformers, heat management, power conditioning). Perform a basic economic analysis to predict the cost reductions necessary such that fuel cell systems can be economically competitive with current energy conversion technologies.

SNF Personal Chemicals in Flammables Storage
Because of space and organizational concerns, storage class L personal
chemicals are being moved from the Flammables cabinets in epi2 area out
to the service area where there is a nice, new flammables cabinet. The
plan is to keep all personal-use chemicals in this new cabinet. The two
Flammables cabinets in the epi2 area will be dedicated to SNF-supplied
chemicals. This means we will be able to stock more high-use chemicals
-- and hopefully avoid running out of Remover PG over a busy weekend.
If you have personal-use chemicals in the Flammables cabinets, please
take a few minutes to make sure they are dated. If they are no longer
in use, please dispose of them. If new yellow labels are needed,
contact Mahnaz or other staff to get new ones. Outdated and unlabeled
chemicals are subject to removal from the lab.
Any questions, please contact the....

Dedicated Wafer Cassette use in SNF
It has been brought to our attention that some people need to be reminded of the policies on dedicated cassettes:
1. No litho cassettes may be taken into the white area of the lab. This includes the metal boats as well as the teflon cassettes with brown buttons.
2. No Furnace preclean or etch cassettes from clean or semiclean stations may be taken into the Litho area of the lab. This includes metal cassettes.
3. To move wafers between the white and litho areas of the lab, use your own transfer cassettes.
4. If you remove a dedicated cassette from a station (for example, from wbdiff to a furnace for loading) return it as soon as possible.
These policies are covered in wet bench training at all these stations. If you need a refresher, refer to the training materials in the website (procedures on the wiki, video at http://spf.stanford.edu/training/wbdiff.wmv.) If everyone is diligent about proper cassette use, the cleanliness in the lab can be better maintained and there should be sufficient cassettes for everyone's use. If you see someone improperly using dedicated cassettes, you have every right to correct that person. You may also report to staff (please provide specific details.)
Thanks for your attention --

Problem p5000etch SNF 2010-03-25 13:57:03: He leak update
It appears the helium leak rate is not calculated until 10sec into the etch step where the valve is opened. If there is a leak problem the error happens and stops the etch at this point. It would be better if the leak rate was checked prior to etch step, so error would not happen after 10sec of the etch step.

Gas flow values did not fluctuate at all during run. Each were at +2sccm from setpoint, and stayed at this value exactly for the whole run. Typically they fluctuate, which might mean they are not being read properly.
EPD also showed very strange drops and rises at random times. This might be due to gasses turning on and off intermitently.

Mini flashlights at etch and deposition tools ....
Thanks to recommendations from Jim Kruger, we've now distributed a
number of small LED flashlights at a variety of etch and deposition
tools where they will, hopefully, be useful for illuminating wafers
through view ports.
Hopefully this will reduce the number of times when you cannot find a
working flashlight when you need one or have to appropriate one from
another tool. Also, the clear case will make it easier to notice that a
flashlight is still on so that we will, hopefully, go through fewer
batteries.

A Start-up's Efforts in DNA Sequencing via Electron Microscopy
J Provine, PhD
Stanford University / Halcyon Molecular
Abstract
There has been significant progress in the past decade to improve the speed and accuracy of genomic sequencing. This technological effort is reaching critical mass as many commercial and academic efforts have continued to increase the pace of innovation. The goal for all those concerned is how to get a complete read of every single base in a genome for low cost (ie < $1000) and at high speed (ie less than 1 hour). In this talk, I will introduce some of the major challenges and players in this effort, discuss our work at Halcyon Molecular and in particular the role of nanostructures and micromachining, and finally give a few short thoughts and lessons learned as a young academic trying to help a start-up.
Biography
J Provine received BA (in Physics), BS (Electrical Engineering), and Masters (also Electrical Engineering) degrees from Rice University in 1998 and 1999. He then received his PhD in Electrical Engineering from Cornell University in 2005 for work on all optical wavelength routers. During his PhD he was able to work at the Berkeley Sensor and Actuator Center where he also was a post-doc for 2005 working on integration of plasmonic filters and MEMS actuators. Since 2006, he has been a research associate at Stanford University working with the Center for Interfacial Engineering in MEMS. In September 2009, he joined Halcyon Molecular part time to aid in their nanofabrication efforts. Before November 2008, you could fit everything he knew about DNA sequencing on this page.

Scalability and Reliability Study of Phase-Change Memory

Advisor: Professor H.-S. Philip Wong
Department of Electrical Engineering, Stanford University
Tuesday, March 16, 2010, 10:00 – 11:00 AM
Paul Allen Building Auditorium (CISX-101)
(Refreshments served at 9:45 AM)
Abstract
Phase-change memory (PCM) is one of the most mature emerging memory technologies. Superior scalability and reliability are important features that phase-change memory (PCM) technology should demonstrate to expand its usage in various memory applications. In the first part of the talk, scalability study of PCM will be presented. The first principle for PCM scaling rule is studied using analytical analysis. As a PCM cell scales down, the interfacial effect becomes more prominent in material properties and device characteristics due to larger surface area to volume ratio. Various structures have been fabricated to measure these interfacial effects and study its impact on the operation of PCM. In search for a high current-density selection-device with low processing temperature which is needed for integration of PCM in a 3-dimensional 4F2 cross-point array, a Ge nanowire diode has been successfully integrated with a PCM memory cell.
In the second part of the talk, reliability related study is presented. Interaction of thermal program-disturb mechanism and temperature dependence of PCM characteristics poses unique challenges for reliability of PCM devices. To study temperature dependence of PCM characteristics, the micro-thermal stage (MTS) with a fast on-chip heater has been integrated with a PCM cell. The MTS enables experimental study on temperature dependence of crystallization time, drift speed, and threshold switching in microsecond time scale. Thermal disturbance and its impact on PCM operation are measured with the MTS and the relevant model is developed. Based on measurement and modeling results, a new scheme is proposed to improve stability of PCM with a short time annealing pulse.
