Hi all,

     Yesterday was the first time I tried out the STS with
the new (20 C) chiller temperature.  All of the 3 wafers I
etched turned out extremely well.  Selectivity vs resist
and oxide was excellent, and the etch rate seems to have
gone up by ~10% as well.  Sidewall angle was about the same
as before.  And of course, no grass!!!
