Hi,

search for "stoney equation" on google, it will provide many useful results.

Best regards,

Oggetto: [mems-talk] residual stress vs. thin film thickness

Dear Everyone,

I am confused with this question for a long time. Does the residual stress
have a relationship with the deposited film thickness?

I have heard that they are independent.

When I measured the residual stress of the low-stress LPCVD SiN, I found
that with the deposited SiN become thicker, the residual tensile stress is
also larger.

Has anybody had this experience?

Sincerely,
