Comment p5000etch SNF 2008-04-02 12:00:58: CH. C process quals run

Used two wafers 1) 3612 PR on Si with resolution mask and 2) blank themal ox wafer.
Results for 1; Si etch rate 2280A/min, PR etch rate 522A/min, selectivity Si:PR = 4.4:1
Results for 2; we need thicker themal ox (or the ox etch rate is more than 930A/min)
