摘要： An impurity adsorption layer is selectively formed from a gas containing an impurity on a semiconductor surface. Solid-phase diffusion of the impurity is effected from the impurity adsorption layer into the semiconductor surface to form a source region and a drain region having a sufficiently small resistivity and an ultrashallow PN junction depth, thereby producing a metal-insulator semiconductor field-effect-transistor featuring fast operating speed and reduced dimensions.

摘要： A method of fabricating a light valve device comprises forming a substrate having stacked layers including a light-shielding thin film layer, an insulating film, and a single crystalline semiconductor thin film stacked in this order on a transparent support substrate. A light-shielding layer pattern is formed by selectively etching the stacked layers. Thereafter, a switching element is formed comprised of a transistor having a channel region formed in the single crystalline semiconductor thin film and a main gate electrode covering the channel region. The channel region is provided over the light-shielding pattern layer to prevent light incident from the transparent support substrate from illuminating the channel region to suppress a photo-induced leakage current in the channel region. A transparent electrode is formed and is electrically connected to the switching element. An opposing substrate is then provided over the substrate at the side of the single crystalline semiconductor thin film, and an electro-optical material layer is interposed between the substrate and the opposing substrate.

摘要： To decrease the area of a chip, improve the manufacturing efficiency and decrease the cost in a semiconductor device such as a driver integrated circuit having a number of output pads, and an electronic circuit device such as electronic clock. There are disposed output pads superposed in two dimensions on driving transistors or logic circuits connected thereto, respectively. Further, not only aluminum interconnection but also bump electrodes or barrier metals are used for the interconnection of the semiconductor device. In a case where a semiconductor integrated circuit is electrically adhered on to a printed circuit board in a face down manner, a solder bump disposed on the semiconductor integrated circuit and the interconnection of the printed circuit board are directly connected to each other, thereby realizing the electrical connection. On this occasion, the bump electrode as the external connecting terminal of the semiconductor integrated circuit is laminated on the transistor.
