  • Patent number: 9773973
    Abstract: A production process in which in an element isolation process for a magnetoresistive effect element, a re-deposited film adhered to a side wall of the element is efficiently removed by ion beam etching. Ion beam etching is performed while a substrate located being inclined relative to the grid is rotated. In the ion beam etching, an energy amount of an ion beam entering from a direction in which a pattern groove formed on the substrate extends is increased larger than the energy amount of the ion beam entering from another direction by controlling a rotation speed of the substrate, and the re-deposited film adhered to the side wall of the magnetoresistive effect element formed on the substrate is efficiently removed by etching.

  • Patent number: 9734989
    Abstract: A film thickness distribution exists in a substrate plane after CMP step. This film thickness distribution results in, for example, variation in gate threshold value voltages of metal gates, and causes variation in element characteristics. It is an object of the present invention to easily improve the film thickness distribution processed by this CMP step. By using the ion beam etching method after the CMP step, the film thickness distribution in the plane of the substrate 111 is corrected. More specifically, when the ion beam etching is performed, the plasma density in the plasma generation chamber 102 is caused to be different between a position facing a central portion in the plane of the substrate 111 and a position facing an outer peripheral portion, so that the etching rate in the central portion in the plane of the substrate 111 and the etching rate in the outer peripheral portion in the substrate plane 111 are caused to be different.

  • Patent number: 9601688
    Abstract: 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.
