Problems with Thick Resist in Etchers

[Jim McVittie]

Lam, P5000, and Amtetcher Users,

We just had major problems in both the Lam and P5000 due a user
etching wafers with thick resist on them. Both machines were brought down
and needed complete manual chamber cleans. PLEASE FOLLOW THE RULES and
stay with thin resist (< 2 um) for wafers going into the Lam, P5000, and
Amtetcher.   

	Thanks,   Jim
