Dicing Method for Stacked Semiconductor Devices
20210358808 · 2021-11-18 ·

A semiconductor structure includes a first device and a second device bonded on the first device. The first device has a first sidewall distal to the second device and a second sidewall proximal to the second device. A surface roughness of the second sidewall is larger than a surface roughness of the first sidewall.
