Then, the press-molded body is sintered. An excellent LC characteristic is obtained even under the sintering condition, and the aluminum-titanium electrolytic capacitor is devoid of bent lead wires.

Abstract: A manufacturing method for an MIS type semiconductor device features in the preferred form a single masking operation used to define source, gate, and drain windows simultaneously in an upper insulating oxide layer disposed over a semiconducting polysilicon layer, the polysilicon layer being separated from the semiconductor substrate by a thin insulating oxide layer serving as the gate oxide. By subsequent deposition of an overall capping nitride layer, followed by selective removal of layers, using relatively low resolution photoresist and portions of the layers themselves as intermediate etching barriers, and by finally converting the polycrystalline layer to an oxide except where it is protected from oxidation by the presence of a nitride stripe over a gate window, the resulting gate electrode is precisely centered between the source and drain windows, and is sealed on all three sides by a protective oxide layer.

Abstract: A method for fabricating an integrated circuit semiconductor device comprised of an array of MOSFET elements having self-aligned or self-registered connections with conductive interconnect lines. The method involves the formation on a substrate of a thick oxide insulation layer surrounding active area openings. A gate electrode within each opening is utilized to provide self-registered source and drain regions. In two embodiments, the gate is covered on all sides and on its top surface with a protective layer of nitride or thick oxide. In one of the embodiments, after the formation of the source-drain regions a relatively thin protective layer of etch stopper is applied to the entire chip prior to the application of an upper insulative layer.

Abstract: A method for hermetically packaging electronic parts such as IC chips within a space defined by a multilayer substrate and a cap is disclosed. A welding rib is formed on the printed circuit board having conductor portions so as to surround those conductor portions over which the electronic parts are to be mounted in a later step. Metal films are formed by nonelectrolytic plating on the conductor portions. A peripheral portion of a cap is placed on the welding rib. A laser beam is radiated onto the contact portion between the peripheral portion and the welding rib so as to weld them together. At this time, a portion of the welding rib which is subject to laser radiation is not covered with the metal film. Welding is thus performed in the absence of phosphorus, which is inevitably contained in the metal film formed by nonelectrolytic plating and is a principal cause of cracking at a welded portion.

Abstract: An automatic rod and reel support carriage apparatus automatically rotates the reel crank to retrieve a line. The apparatus provides a weighted base frame upon which is securely fastened a motordrive. A rotating hub provides radially spaced recesses which engage the reel crank. A carriage is also supported by the base for holding the reel in a position which engages the reel crank with the hub.
