Latest Patents

One of Yoshio Hayashide's latest patents is a method of making a semiconductor device having a planarized surface. The objective of this invention is to effectively reduce differences in level in a short time for convex patterns that spread horizontally on a large scale. The process involves forming an insulating film on a semiconductor substrate to cover the convex pattern and fill in any concave portions. A portion of the insulating film located on the planarized section of the convex pattern is selectively etched away, leaving a frame-shaped insulating film on the outer periphery of the convex pattern. The remaining insulating film on the semiconductor substrate is then etched using a chemical/mechanical polishing method, resulting in a planarized surface of the semiconductor substrate.
