Gate oxides formed from elements such as zirconium are thermodynamically stable such that the gate oxides formed will have minimal reactions with a silicon substrate or other structures during any later high temperature processing stages. The process shown is performed at lower temperatures than the prior art, which further inhibits reactions with the silicon substrate or other structures. Using a thermal evaporation technique to deposit the layer to be oxidized, the underlying substrate surface smoothness is preserved, thus providing improved and more consistent electrical properties in the resulting gate oxide.

    Abstract: A semiconductor element of the electric circuit includes a semiconductor layer over a gate electrode. The semiconductor layer of the semiconductor element is formed of a layer including polycrystalline silicon which is obtained by crystallizing amorphous silicon by heat treatment or laser irradiation, over a substrate. The obtained layer including polycrystalline silicon is also used for a structure layer such as a movable electrode of a structure body. Therefore, the structure body and the electric circuit for controlling the structure body can be formed over one substrate. As a result, a micromachine can be miniaturized. Further, assembly and packaging are unnecessary, so that manufacturing cost can be reduced.

The transparent conductive film-side surface of the underlying layer is provided with a pyramid-shaped or inverse pyramid-shaped irregular structures, and the transparent conductive film comprises a first transparent electrode layer which is formed on the underlying layer and a second transparent electrode layer which forms the outermost surface of the transparent conductive film. By forming a zinc oxide layer that serves as the second transparent electrode layer by a reduced pressure CVD method, a substrate with a transparent conductive film that is provided with an irregular structure smaller than that of the underlying layer can be obtained. The substrate with a transparent conductive film can improve the conversion efficiency of a photoelectric conversion device through an increased light trapping effect.
