Abstract:
1. A method of manufacturing a magneto-resistive device comprising the steps of: depositing constituent layers which make up a magneto-resistive layer on a base; patterning one or more layers of said constituent layers; and forming an insulating layer in a region in which said one or more layers of said constituent layers have been removed by the patterning; wherein said step of forming said insulating layer includes the step of depositing said insulating layer while irradiating an ion beam of a gas mainly containing a rare gas toward said base after said step of patterning; wherein said step of depositing said insulating layer includes the step of using an ion beam deposition system having a first gun and a second gun so as to irradiate a target irradiating ion beam toward a target of said insulating layer from said first ion gun while irradiating the ion beam of the gas mainly containing the rare gas toward said base from said second ion gun.
