Title: Qiaoming Cai: Semiconductor Structure and Gate Formation
Introduction
Qiaoming Cai is an inventor based in Beijing, China. His work includes semiconductor device structures and methods for forming them.
Latest Patents
Cai is associated with 1 patent, titled “Semiconductor Structure and Method for Forming Same.” The patent describes a process for forming discrete poly gate layers in two regions of a base. In the first region, a bottom gate layer and a protruding top gate layer define a groove, with a polish block layer formed along its sidewall. After an interlayer dielectric layer is formed, the poly gate layer in the second region is removed to create a gate opening, which is then filled with a metal gate layer. The disclosed approach concerns semiconductor structure fabrication and gate formation.
