  • Publication number: 20210272840
    Abstract: A method of manufacturing a semiconductor device includes a first deposition process, a second deposition process, an oxidation process, and a desorption process. In the first deposition process, a thermally decomposable organic material on a substrate in which a recess is formed, is deposited. In the second deposition process, a metal layer is deposited on the organic material by sputtering, which uses a target containing metal. In the oxidation process, the metal layer is oxidized. In the desorption process, an air gap is formed between the oxidized metal layer and the recess by heating the substrate at a predetermined temperature to thermally decompose the organic material to desorb the organic material under the oxidized metal layer through the oxidized metal layer.

  • Patent number: 11079850
    Abstract: In an input apparatus, under a state where contact of a manipulating body to a predetermined position on a manipulation surface is detected, a second low frictional force between the manipulation surface and the manipulating body is provided by vibrating the manipulation surface. The second low frictional force is smaller than a frictional force between the manipulation surface and the manipulating body when the manipulation surface is not vibrated. In response to determining the movement of the manipulating body from the predetermined position towards a target position on the manipulation surface, a first low frictional force between the manipulation surface and the manipulating body is provided by a predetermined time by vibrating the manipulation surface. The first low frictional force is smaller than the second low frictional force.
