Patent number: 7477003Abstract: There is provided a bimorph element including a silicon oxide layer, a high expansion coefficient layer that is formed on the silicon oxide layer and has a thermal expansion coefficient higher than a thermal expansion coefficient of the silicon oxide layer, and a deformation preventing film that covers a surface of the silicon oxide layer and prevents the silicon oxide layer from being deformed over time. The deformation preventing film has a transmission factor of moisture and oxygen lower than that of the silicon oxide layer. The deformation preventing film is a silicon oxide film that is formed with energy higher than that used in a case that forms the silicon oxide layer. The deformation preventing film is a silicon nitride film or a metallic film.Type: GrantFiled: March 1, 2007Date of Patent: January 13, 2009Assignee: Advantest CorporationInventors: Fumikazu Takayanagi, Hirokazu Sanpei

Patent number: 7466065Abstract: A bimorph switch electrically connecting a traveling contact and a fixed contact. The switch comprises a substrate having a front face, a rear face, and a through hole penetrating from the front face to the rear face; a fixed contact extending from an edge portion of the aperture of the through hole towards the inside of the aperture; and a bimorph section holding the traveling contact at a position facing the aperture and driving the traveling contact. One end of the bimorph section may be formed on a silicon oxide layer formed on a front face of the substrate.Type: GrantFiled: August 15, 2006Date of Patent: December 16, 2008Assignees: Advantest CorporationInventors: Hirokazu Sanpei, Jun Mizuno, Masazumi Yasuoka, Humikazu Takayanagi, Takehisa Takoshima, Masaru Miyazaki, Masayoshi Esashi
