摘要： A method of selectively depositing tungsten upon a silicon semiconductor substrate. A silicon substrate is coated with a masking film of PSG or SiO.sub.2 that is patterned to provide an opening for forming an electrode or wiring. On a portion of the substrate in the opening, a layer of tungsten having a thickness of approximately 2000 .ANG. is deposited by a CVD method from an atomosphere containing a gaseous mixture of WF.sub.6 and H.sub.2 . During this processing, tungsten nucleuses deposit on the surface of the masking film as well. Before such nucleuses form a film, the deposition processing is discontinued and H.sub.2 gas is fed into the CVD apparatus to produce HF, which etches the surface of the masking film, and thus tungsten nucleuses are removed. The deposition and removal steps are repeated several times until the height of the deposited tungsten and the thickness of the masking film are essentially equal to present a flat surface. Aluminum film is deposited on the flat surface and patterned by lithography. The flat aluminum deposition allows fabrication of accurate and reliable wirings and facilitates production of VLSI of sub-micron order.

摘要： A plasma CVD apparatus for forming a deposited film on a base body by introducing a gas of a compound into a chamber and converting the gas into plasma by applying a high frequency electric power, includes a gas feeding pipe leading from the exterior of the chamber into the interior of the chamber, and a heating device. The heating device heats at least a part of the gas feeding pipe inside the chamber, thereby preventing the gas from condensing or solidifying. With this apparatus, plasma CVD can stably be carried out using gases of various compounds which are liquid or solid at room temperature.

摘要： A semiconductor device having a deposited phosphosilicate glass film, containing an insubstantial amount of hydrogen and a low phosphorus concentration, is manufactured at a high mass productivity. This semiconductor device is manufactured by first placing plural substrates for semiconductor devices to be treated in a reaction tube so that the main surfaces of the substrates are substantially vertically aligned with respect to one another and are substantially perpendicularly intersected by the central axis of the reaction tube, the reaction tube being provided with at least two gas feed pipes having plural small openings pierced along the longitudinal direction thereof. Second, a silicon compound gas is introduced through one of the gas feed pipes into the reaction tube and an oxidizing gas is introduced through the other of the gas feed pipes into the reaction tube, while the inside of the reaction tube is maintained a reduced low pressure, whereby phosphosilicate glass films are deposited on the main surfaces of the substrates.

摘要： A bipolar transistor includes a base region made of silicon crystal doped with a first impurity to a first level so as to establish a first carrier concentration in the base region and an emitter region made of silicon crystal doped with a second impurity to a second level substantially larger than the first level by a predetermined factor so as to establish a second carrier concentration in the emitter region, in which the second impurity exceeds the solubility limit of the second impurity in silicon crystal. The first and second levels are chosen in such a range that a difference in the carrier concentrations between the emitter region and the base region decreases substantially with increasing impurity level in the base region.

摘要： A method of plasma enhanced chemical vapor deposition of a phosphosilicate glass film on a substrate from a reaction gas mixture including SiH.sub.4, N.sub.2 O and PH.sub.3 is disclosed. This deposition is effected under the conditions such that a mol ratio of N.sub.2 O to SiH.sub.4 (N.sub.2 O/SiH.sub.4) in the reaction gas mixture is 50 or more and that a mol ratio of PH.sub.3 to SiH.sub.4 (PH.sub.3 /SiH.sub.4) in the reaction gas mixture is 0.08 or less. In the phosphosilicate glass film thus deposited, no cracking occurs due to a high temperature heat-treatment and due to the stress, caused by cooling the deposited films to an ordinarily ambient temperature.

摘要： A process for high pressure oxidation of silicon comprising the steps of inserting silicon wafers and an oxidizing substance into a quartz capsule sealing the quartz capsule gas-tightly by fusing, and heating the quartz capsule to generate a high pressure oxidizing atmosphere therein and to form an oxide film on the silicon wafers without a flow of the oxidizing atmosphere. In a case where water is used as the oxidizing substance, the water is frozen and the inside space of the quartz capsule is exhausted before the sealing operation. Furthermore, in a case where an oxidizing gas, e.g. oxygen gas, is used as the oxidizing substance, if the pressure of the gas is higher than the ambient pressure, the quartz capsule is cooled to decrease the gas pressure to a pressure below the ambient pressure before the sealing operation.

摘要： A system for sampling binary value images of white and black and efficiently encoding and decoding them is disclosed. An image is sampled to form a plurality of small picture cells. The small picture cells are merged in groups of four to form a plurality of large picture cells. At least one least frequently occurring density level is determined for the plurality of large picture cells. The least frequently occurring density level is converted to an adjacent density level. The density levels for the picture cells are then encoded and transmitted to a receiver. At the receiving end, the encoded large picture cells are decoded to form a plurality of restored large picture cells. Each restored large picture cell is divided into four small restored picture cells by comparing its density level with that of four neighboring large restored picture cells.
