Material request: ZnS

[Jim McVittie]

Ben,

Some of the students already work with ZnCdS, so ZnS is not new to the
lab. I think they have done some sputter etching of their material in the
MRC. I will have to check on this point.  What materials do you want to
etch? To plasma etch ZnS, you need a CH4/H2/Ar process, which we do not 
have.
