摘要： Integrated circuits having complementary metal-oxide semiconductor (CMOS) and photonics circuitry and techniques for three-dimensional integration thereof are provided. In one aspect, a three-dimensional integrated circuit comprises a bottom device layer and a top device layer. The bottom device layer comprises a substrate; a digital CMOS circuitry layer adjacent to the substrate; and a first bonding oxide layer adjacent to a side of the digital CMOS circuitry layer opposite the substrate. The top device layer comprises an analog CMOS and photonics circuitry layer formed in a silicon-on-insulator (SOI) layer having a buried oxide (BOX) with a thickness of greater than or equal to about 0.5 micrometers; and a second bonding oxide layer adjacent to the analog CMOS and photonics circuitry layer. The bottom device layer is bonded to the top device layer by an oxide-to-oxide bond between the first bonding oxide layer and the second bonding oxide layer.
