    摘要: A semiconductor production apparatus employs a target prepared by using a solder alloy which has a limited Sn content. The solder alloy can form an alloy layer having large elongation between a metal target and a backing plate to prevent undesirable cracking and separation of target, whereby a semiconductor device can be produced with a high degree of reliability.

    摘要: Silicon substrate is provided with silicon single-crystalline wafer, natural oxide film and poly-crystalline silicon film. The thickness of natural oxide film is controlled to be less than 10 .ANG.. Since the thickness of natural oxide film is made less than 10 .ANG., heavy metals travel smoothly from silicon single-crystalline wafer to poly-crystalline silicon film in the process of gettering. In other words, it is possible to enhance gettering effect.

    摘要: In order to lessen the deterioration of the VSWR, a plural-reflector antenna system is provided wherein an appropriately shaped vertex matching plate is disposed on the subreflector and electric waves that reenter the primary radiator are cancelled out. The electric waves radiated from the primary radiator are reflected by the subreflector and are radiated into space after being reflected by the main reflector. The passing area in the horn aperture, through which the reflected waves from the vertex matching plate pass, is made to be analogous to the aperture of the primary radiator, by defining the vertex matching plate as an ellipsoid, and by orienting its minor-axis direction in the major-axis direction of the main reflector and its major-axis direction, in the minor-axis direction of the main reflector.

    摘要: A semiconductor device without erroneous operation and deterioration of characteristics in a transistor even when an impurity region is formed in self-alignment by ion implantation using a gate electrode as a mask, and a method of manufacturing thereof are disclosed. This semiconductor device includes a gate electrode formed of a polycrystal silicon layer 4b having the crystal orientation of the crystal grains arranged in a definite orientation. By implanting ions at a predetermined angle with respect to the crystallographic axis of the crystal grains of the polycrystal silicon layer 4b in forming a p.sup.+ impurity region 5 by ion implantation using the gate electrode as a mask, the channeling phenomenon where ions pass through the gate electrode is prevented. Therefore, generation of erroneous operation and deterioration of characteristics in a transistor are prevented in forming an impurity region in self-alignment by ion implantation using the gate electrode as a mask.
