Latest Patents

Andrews holds a patent for a method titled "Low cost shallow trench isolation using non-conformal dielectric material." This innovative approach provides a method for planarizing a structure such as a shallow trench isolation region on a semiconductor substrate. The patent describes a semiconductor substrate with raised and lowered regions featuring 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 to a predetermined thickness. This process allows for the selective removal of raised regions of the filler material without affecting the filler material in the lowered regions.
