Latest Patents

Yongcheng Wang holds a patent for a method of filling shallow trenches. This method involves successively forming a first oxide layer and a second oxide layer over the surface of a silicon substrate where shallow trenches are formed. The process includes etching the second oxide layer to create inner sidewalls using an etchant with a high etching selectivity ratio. Following this, a high-quality pad oxide layer is grown through thermal oxidation after the inner sidewalls are removed. Finally, the trenches are filled with an isolation dielectric material. This innovative method reduces the risk of junction spiking and electrical leakage during the subsequent process of forming a metal silicide. Yongcheng Wang has 1 patent to his name.
