Subject: [mems-talk] pyrex/pyrex anodic bonding

Hi,

I am trying to bond a pyrex wafer to another 4 inch pyrex wafer by anodic
bonding.  For that I use an amorphous silicon deposited by PECVD as intermediate
layer (less than 1 µm thickness) or polysilicon deposited by LPCVD.  The
parameters which I use are: 450°C on both wafers, 1200 V and 200N, but in both
case I don't have a good bonding. if you have any suggestions, they will be
welcome.

best,

Alaa
