摘要:
Using the title semiconductor device, a synapse circuit through which no steady-state current flows, whose positive and negative weights can be realized by a single 5-V current, and which has a self-learning function is realized. This semiconductor device comprises first and second power source lines which supply high and low two potentials a first NMOS having a first floating gate, and a second PMOS having a second floating gate. The source and drain of the first NMOS are connected to the second and first power source lines through third NMOS and fourth PMOS, respectively. The source and drain of the second PMOS are connected in the first and second power source lines through fifth PMOS and sixth NMOS, respectively. The sources of the first NMOS and second PMOS are connected to the thrid floating gate through first and second capacitors, respectively.
摘要:
A gas supply pipeline system for process equipment, adapted to supply at least two kinds of process gas, and provided with at least two valves (135, 136, 139, 140) installed in each of independent flow passages formed between process gas supply pipelines and a purge gas supply pipe line, and at least two valves (137, 138, 141, 142) installed in each of a plurality of flow passages formed between the process gas supply pipelines and the pipelines in the process equipment. Each of the process gas supply pipelines and each of the pipelines in the process equipment can be purged and vacuumed by at least two valves in each of these flow passages that are opened or closed independently, and the stagnation of a gas in the pipelines not in use can be prevented by introducing a purge gas constantly thereinto.

A method and apparatus for transportation of wafers from one stage to another in a manufacturing process while protecting clean silicon surfaces and thin films on them from contamination through the air. The apparatus includes a wafer container (101) having a gas inlet (103) and a gas outlet (112), an inert gas container (103) having an inert gas sealed therein, and a piping (114) for connecting the gas inlet (113) of the wafer container to the inert gas container (103) and for sending the inert gas in the inert gas container to the wafer container (114), and wafers are transported while the inside of the wafer container is constantly purged by introducing the inert gas.
摘要:
A method for cleaning an object and an apparatus therefor, which uses a substance alternative to chlorofluorocarbon and having a detergency equal to that of chlorofluorocarbon. When a pure water including ozone (e.g., a concentration of 1.5 ppm) is sprayed on the object (6) to be treated, extraneous substances adhering on the object are removed completely from the object by the oxidation by ozone.
摘要:
An element which includes a first film containing no impurity particles due to spontaneous oxidization or residual resist at its surface, and an electrically conductive material layer formed on a surface in contact with the surface of said first film. On the surface of the electrically conductive material layer is formed an insulating compound film as a result of surface reaction with the electrically conductive material layer, and on the surface of said first film is formed a desired second film that is necessary for constituting the element.
摘要:
A method of fabricating semiconductor devices and, particularly, an art for forming thin-film semiconductor elements on a substrate. The fabrication method comprises a step for forming a conductor layer having a step on at least a portion on one main surface of the substrate, and a step for forming a semiconductor thin film on the substrate under the condition where a dc potential is being given to the conductor layer. The low-temperature process of the invention makes it possible to easily form a single- crystal semiconductor layer of high quality on any insulating substrate. Therefore, very high-speed semiconductor devices and high-performance flat panel displays can be manufactured.

A semiconductor device in which field-effect transistors are fabricated on the surface of silicon substantially having direction of crystal plane. The field-effect transistors are so arranged on the silicon surface that the direction from the source region of each field-effect transistor to the drain region thereof substantially agrees with the direction of crystal plane.
摘要:
A valve in accordance with the reduction in diameter of piping in a vacuum discharge system, the reduction realizing downsizing of apparatuses for a vacuum discharge system and resultant reduced costs and shortened time for vacuum discharge. In the valve, inside corrosion, clogging, seat leakage, etc. by accumulation of dissociated products produced by decomposition of gas can be prevented from occurring. Specifically, passive aluminum is used for piping components, such as the valve, adapted for a vacuum discharge system so as to control decomposition of gas caused by rise in temperature during baking, so that components suitable for the reduction in diameter sizes in the vacuum discharge system are provided. Corrosion, clogging, seat leakage, etc. caused by decomposition of gas are prevented from occurring.
摘要:
An apparatus for producing a gas using a raw material gas having high reactivity, in particular, a fluorinated hydrocarbon, or a vessel for supplying the gas, characterized in that the surface of a portion thereof contacting with the gas has an average roughness of 1 µm or less in terms of a center line average roughness Ra. It is preferred that an oxide-based passivated film such as a film based on chromium oxide, aluminum oxide, yttrium oxide, magnesium oxide or the like is formed on the surface having a roughness controlled as above. The above apparatus and vessel can be suitably used for preventing the contamination of a raw material gas originated from a gas production apparatus or a vessel for supplying the gas.
