Latest Patents

Arthanari holds 1 patent for his innovative method titled "Shallow trench isolation using non-conformal dielectric and planarization." This patent describes a method for planarizing a structure such as a shallow trench isolation region on a semiconductor substrate. The process involves providing a semiconductor substrate with raised and lowered regions that have substantially vertical and horizontal surfaces. The lowered regions correspond to trench regions, which are covered by a masking layer of nitride with a predetermined thickness. Filler material, such as non-conformal high-density plasma oxide, is deposited over the horizontal surfaces to a thickness that terminates within that of the nitride layer. The raised regions of the filler material are selectively removed in a single planarizing step without affecting the filler material in the lowered regions, using a fixed abrasive hard polishing pad instead of an abrasive slurry.
