Abstract: Disclosed is a powder atomic layer deposition equipment with a quick release function, comprising a vacuum chamber, a shaft sealing device, and a driving unit connected to the shaft sealing device. The vacuum chamber is connected to the shaft sealing device, and an enclosed space is formed between the vacuum chamber and the shaft sealing device. At least one air extraction line is located in the shaft sealing device and fluidly connected to the enclosed space, the air extraction line being used in pumping gas out from the enclosed space to fix the vacuum chamber to the shaft sealing device so that the drive unit rotates the vacuum chamber via the shaft sealing device to facilitate the formation of a uniform thin film on powder surface. When the pumping stops, the vacuum chamber can be quickly released from the shaft sealing device to improve the process efficiency and convenience of use.

Abstract: A microelectromechanical system (MEMS) structure and method of forming the MEMS device, including forming a first metallization structure over a complementary metal-oxide-semiconductor (CMOS) wafer, where the first metallization structure includes a first sacrificial oxide layer and a first metal contact pad. A second metallization structure is formed over a MEMS wafer, where the second metallization structure includes a second sacrificial oxide layer and a second metal contact pad.
