  • Publication number: 20130271418
    Abstract: In a piezoelectric oscillation device in which a support substrate is oscillated using a bimorph-type piezoelectric oscillation element, the click sensation when the support substrate is operated is improved, and shock resistance of a control panel is improved. Provided is a piezoelectric oscillation device in which wiring is not easily broken. On the rear side of a touch panel (16), one main surface of a bimorph-type piezoelectric oscillation element (20) is entirely bonded via an elastic body (18) having a tensile elasticity of 20-100 MPa as measured according to JIS K7161. The piezoelectric oscillation element (20) has surface electrode layers (30A, 30B) connected to terminal electrodes (36A, 36B) via wiring lines (38A, 38B). The wiring lines (38A, 38B) are formed on top of a wiring protection layer (32) made of an elastic body provided on the rear side of the touch panel (16), and because the wiring lines can move following the displacement and are therefore resistant to breakage.

  • Publication number: 20130043467
    Abstract: With a TFT using an oxide semiconductor film, there is such an issue that oxygen deficit is generated in a surface region of the oxide semiconductor film after performing plasma etching of a source/drain electrode, thereby increasing the off-current. Provided is a TFT which includes: a gate electrode on an insulating substrate; a gate insulating film on the gate electrode; an oxide semiconductor film containing indium on the gate insulating film; and a source/drain electrode on the oxide semiconductor film. Further, the peak position derived from an indium 3d orbital in the XPS spectrum of a surface layer in a part of the oxide semiconductor film where the source/drain electrode is not superimposed is shifted towards a high energy side than the peak position derived from the indium 3d orbital in the XPS spectrum of an oxide semiconductor region existing in a lower part of the surface layer.
