Hello,

I need information of how to reduce the stress gradient in the aluminum
layers in a surface micromachining process containing polyimide as a
sacrificial and aluminum as strcural layer.

The polyimide is spun to 5 micron and cured at 220degrees. The aluminum
was evaporated at about 0.1microTorr with 15Angs/sec rate.

Thank you

Ofir Degani
