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

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?
