    摘要: A semiconductor device is provided that can be manufactured by a simpler process than a conventional lateral trench power MOSFET for use with an 80V breakdown voltage, and which has a lower device pitch and lower on-state resistance per unit area than a conventional lateral power MOSFET for use with a lower breakdown voltage than 80V. A gate oxide film is formed thinly along the lateral surfaces of a trench at a uniform thickness. Then, a gate oxide film is formed along the bottom surface of the trench by selective oxidation so as to be thicker than the gate oxide film on the lateral surfaces of the trench and so as to become progressively thicker from the edge of the bottom surface of the trench toward drain polysilicon.

    摘要: To reduce the on-resistance in a semiconductor device, such as a trench lateral power MOSFET, a trench etching region forms a mesh pattern in which a first trench section, formed in an active region, and a second trench section, formed in a gate region for leading out gate polysilicon to a substrate surface, intersect each other. An island-like non-trench region, which is left without being subjected to etching, is divided into a plurality of smaller regions by one or more third trench section that connect with the first and second trench sections that form the mesh pattern. In each non-trench region, a contact section for connecting a drain region (or a source region) and an electrode is formed so as to be spread over all of the smaller regions in the non-trench region.

    摘要: This invention aims to provide a laminated structure and an integrated structure of a high production efficiency for a CIS based thin-film solar cell, which can produce a high-resistance buffer layer of the CIS based thin-film solar cell efficiently on a series of production lines and which needs no treatment of wastes or the like, and a manufacturing method for the structures. The CIS based thin-film solar cell includes a back electrode, a p-type CIS based light absorbing layer, a high-resistance buffer layer and an n-type transparent conductive film laminated in this order. The high-resistance buffer layer and the n-type transparent conductive film are formed of thin films of a zinc oxide group. The buffer layer contacts the p-type CIS based light absorbing layer directly, and has a resistivity of 500Ω·cm or higher.

    摘要: A treatment object containing any one of Cu/Ga, Cu/In and Cu—Ga/In is held in a heated state at a temperature T1 for a time Δt1 in such a state that a selenium source is introduced, thereby forming a selenide. Thereafter, a sulfur source is introduced to replace the atmosphere in the system with a sulfur atmosphere. In this state, the treatment object is held in a heated state at a temperature T2 for a time Δt2. The temperature of the treatment object is then decreased to T3, and, at that temperature, the treatment object is held in a heated state for a time Δt3.
