Abstract

The disclosure provides a method of manufacturing a semiconductor device including bonding a second device wafer to a first device wafer, such that a first bonding interface including a dielectric-to-dielectric bonding interface and a metal-to-metal bonding interface is formed between the first device wafer and the second device wafer, wherein the second device wafer is electrically coupled to the first device wafer, and a function of the first device wafer and the second device wafer are the same kind of device wafer. A semiconductor device is also provided.
