Request to etch polymer

[Jim McVittie]

Yashesh,

Do you have any info on the vapor pressure of Waferboond at a T of 180C. 
In the Matrix the wafer is usually heated to about 180C if my memory is 
correct. You lower the temperature by running with the pins up but the 
etch is temperature dependent (Ea ~ 1 eV). If there are any metals in the 
glue/wax, they will be oxidized and will be hard to get off. Do you have 
any data on anyone who has use a asher to strip Waferbond?

	Thanks, Jim
