Drytek2 Users,
Several in chamber water leaks were repaired, chamber was
seasoned for 1 hr with poly etch process and uniform ER test
was performed at top wafer position. Using 5 pt measurement
(center and 1 cm from edges), etch rate (ER) was found to be
1611 +/- 13 A/min. Next week, I will work with Henry to minimizethe electrode to electrode non-uniformity. Many thanks to Len
and Cesar for repairing the leaks.
