Latest Patents

Er Hu Zheng's latest patents include a semiconductor structure and fabrication method. This invention provides a semiconductor device and a fabrication method that involves several intricate steps. The method includes providing a gate structure on a substrate and a first protective layer on the gate structure. It also involves forming an initial sidewall spacer on the sidewall of each gate structure and the first protective layer. Additionally, a first sidewall spacer is formed on the sidewall of the initial sidewall spacer, with both spacers made of different materials. The process continues with the formation of a second sidewall spacer by removing a portion of the initial sidewall spacer, creating a trench above the second sidewall spacer. The second protective layer is then formed in the trench, ensuring that it and the first sidewall spacer are made of the same material. The second sidewall spacer has a top surface that is higher than or level with the top surface of the gate structure.

Another notable patent by Zheng is an etching method and fabrication method of semiconductor structures. This method includes forming trenches in a to-be-etched structure and creating a dielectric layer within those trenches. The etching process involves controlling the etching temperature while a polymer is formed on the side surface of the to-be-etched structure. During this process, the polymer undergoes both a deposition stage and a removal stage, with varying rates that are crucial for the etching process.
