Latest Patents

Qichao Liang holds a patent for a method for manufacturing a semiconductor device. This patent outlines a detailed process that includes several key steps. The first step involves forming first gate structures on a semiconductor substrate. The second step is a first etching process that etches the semiconductor substrate on at least one side of each first gate structure to a certain depth, forming a first groove. The third step is a stress memorization process, which includes forming a stress dielectric layer that covers the peripheral surface of each first gate structure and fills the first groove. This is followed by an annealing process to transfer the stress of the stress dielectric layer to the channel region, and finally, the removal of the stress dielectric layer. This innovative method enhances the mobility of channel carriers, thereby improving the performance of semiconductor devices.
