Latest Patents

Fumiaki Saitoh holds a patent for a "Method of manufacturing semiconductor device." This method enables control of impurity concentration and fine patterning by making the removal of residual stress due to LOCOS oxidation compatible with the formation of deep wells. A selective oxide layer is formed to separate element regions on a principal plane of a semiconductor substrate, such as a p.sup.- -type silicon substrate. A mask is created on the surface, including the selective oxide layer, and impurities like phosphorous are introduced through an opening in the mask. The selective oxide film is then annealed by high-temperature treatment while a deep well, such as an n-type deep well, is formed by introducing the impurities. This innovative approach enhances the efficiency and effectiveness of semiconductor devices.
