Latest Patents

Qiu Ling Jia holds a patent for a "Power MOSFET with metal filled deep sinker contact for CSP." This invention involves a method of forming an integrated circuit that includes a power semiconductor device. The process begins with providing a substrate that has an epi layer, where at least one transistor is formed and covered by a pre-metal dielectric (PMD) layer. Contact openings are etched through the PMD into the epi layer, creating a sinker trench that extends to a first node of the device. A metal fill material is deposited to cover the sidewall and bottom of the sinker trench without completely filling it. A dielectric filler layer is then deposited over the metal fill material to fill the trench. The overburden region of the dielectric filler layer is removed, stopping on the surface of the metal fill material, to form a sinker contact. Finally, a patterned interconnect metal is formed to connect the interconnect metal and the metal fill material on the sidewall of the sinker trench.
