Latest Patents

Fukuya holds a patent for a "Method of making current-perpendicular-to-the-plane structure magnetoresistive head." This invention involves a unique approach where the lower electrode is exposed at the surface of a substructure layer in a current-perpendicular-to-the-plane structure magnetoresistive element. A resist is formed to extend over the surface of the substructure layer, and a patterning void is defined in the resist. The design of the patterning void corresponds to the contour of the magnetoresistive multilayered film, which is formed by deposition within the void. This method effectively avoids the dry etching process typically used on the magnetoresistive multilayered film, ensuring that no scrapings or waste are generated. The side surfaces of the film remain free from attachment or adhesion of scrapings, maintaining their cleanliness.
