Patent number: 9601688Abstract: In a case where reactive ion etching using a gas containing an oxygen atom is used for etching or a magnetoresistive element, a magnetic film becomes damaged due to oxidation. Such damage to the element by the oxidation becomes a factor which causes deterioration in element properties. In the etching of the magnetoresistive element according to one embodiment of the present invention, a magnetoresistive film is subjected to ion beam etching and thereafter to reactive ion etching. A side deposition formed by the ion beam etching coats a sidewall of the magnetoresistive film and reduces damage by the oxygen atom during the later reactive ion etching. Also, a time during which the element is exposed to plasma of the gas containing the oxygen atom can be reduced.Type: GrantFiled: February 20, 2014Date of Patent: March 21, 2017Assignee: Canon Anelva CorporationInventor: Masayoshi Ikeda
