Latest Patents

One of Bao T Hwang's key patents is titled "Low cost shallow trench isolation using non-conformal dielectric material." This patent describes a method for planarizing a structure, such as a shallow trench isolation region on a semiconductor substrate. The method involves providing a semiconductor substrate with raised and lowered regions that have substantially vertical and horizontal surfaces. The lowered regions correspond to trench regions, and filler material, such as non-conformal high-density plasma oxide, is deposited over the horizontal surfaces. This process ensures that the filler material reaches a predetermined height, creating distinct raised and lowered regions. The raised regions can then be selectively removed without affecting the filler material in the lowered regions. This innovative approach has the potential to enhance the efficiency and cost-effectiveness of semiconductor manufacturing.
