Title: Dry etching apparatus
Inventor: NISHIMORI SHIGERU
IPC: H01L21/22
Filed: 1988-08-24
Abstract: PURPOSE:To prevent a piping from being clogged and to improve reliability of etching operation by providing an electrode arranged within a reaction chamber with a gas piping for supplying into the piping a gas mixture in which high-and low-temperature gases are mixed properly to regulate the temperature thereof so that the temperature of a semiconductor wafer is controlled thereby. CONSTITUTION:In an ion etching process, temperature of a semiconductor wafer 4 is increased along with increase of temperature of a lower electrode by ion acceleration. Therefore, the-temperature of the lower electrode 3 should be held at a predetermined value. For this purpose, the lower electrode 3 is provided with a piping 7 for temperature regulation, and a hightemperature gas pipe 10 and a low-temperature gas pipe 11 are connected to the input side of the piping 7 so that an inert gas at a temperature higher than the set temperature and an inert gas at a temperature lower than the set temperature are supplied therefrom via flow regulating valves 8 and 9, respectively. Closing of the flow regulating valves is controlled by a controller 13 to which a signal from a temperature sensor 12 provided in the lower electrode 3 is inputted, so that flows and proportions of the high- and low-temperature gases supplied into the piping 7 are regulated properly to hold the temperature of the lower electrode 3 at the predetermined value. In this manner, the temperature of the semiconductor wafer 4 can be controlled with high precision.

Title: Manufacture of bundled and cured short carbon fiber chip
Inventor: HARAGUCHI KEIICHI
IPC: B29B9/14
Filed: 1986-09-10
Abstract: PURPOSE:To obtain short carbon fiber chips, which have favorable workability and excellent dispersibility into matrix, by a method wherein carbon fiber continuous strands, which are bundled by crosslinked resin, are contained with liquid and, after that, cut. CONSTITUTION:Carbon fiber continuous strands, which are sized by crosslinked resin, are intended to be turned into short fiber chips, the carbon fiber continuous strands are contained with liquid and cut after that. As the liquid used at this time, any liquid, which does not remarkably dissolve sizing agent and the temperature necessary for drying which is 200 deg.C or lower, will do. The optimum liquid used is water. Under the conditions just mentioned above, even when the strands are sized by hard crosslinked resin, the impact force at cutting is absorbed by the liquid, which is contained among the strands, and the strands do not break up in single yarns and consequently have high bulk density and favorable workability at normal temperature. In addition, because the sizing agent resin is crosslinked, the strands do not get adhesion during the handling and process under comparatively high temperature, resulting in allowing to obtain chips excellent in workability.

Abstract: PROBLEM TO BE SOLVED: To continuously and rapidly control a hydrocarbon heat content of a partially oxidizing apparatus feed gas flow by measuring a hydrocarbon heat content of a raw material feed gas flow and adjusting the flow rate of the partially oxidizing apparatus feed gas based on the measured value.  
     SOLUTION: A hydrocarbon heat content HO of a raw material feed gas flow is measured and a signal which represents the heat content HO is set and the signal is transmitted to an evaluation means. Then in the evaluation means, the heat content HO is compared with designed hydrocarbon heat content HD of a partially oxidizing apparatus fed gas and when HO is larger than HD, flow rate FO of raw material feed gas flow is determined according to formula I(FD is designed flow rate of partially oxidizing apparatus feed gas flow) and when HO is not larger than HD, the flow rate FO is determined according to formula II and further a flow rate FR of re-utilizing gas flow is determined according to formula III. Then, flow rate of the raw material feed gas flow and flow rate of the re-utilizing gas flow are adjusted according to calculated FO and FR. Then, the two gas flows are mixed to form a partially oxidizing apparatus feed gas flow and the mixed gas flow is partially oxidized to produce a synthetic gas mixture composed of carbon monoxide and hydrogen.

Abstract: PURPOSE:To improve the dielectric strength by patterning an antioxidant/ antireflection film simultaneously with a single crystal silicon film to form an island-like element area, and generating a thick SiO2 film inside the element area by oxidizing the antioxidant/antireflection film as a mask. CONSTITUTION:On an SiO2 film 2 which is generated on a silicon substrate 1, a polycrystal silicon film 3 is adhered by the CVD method.

Then a capped layer 20 and the single crystal silicon film 3 are patterned, while leaving the capped layer 20 as it is, by the photoprocess so that an island-like element area can be separated. Then an SiO2 film 9 is formed at the side surface of the single crystal silicon film 3 (island-like element area) by wet-oxidizing at 900 deg.C. According to the constitution, it is made possible to form a thick SiO2 film on the side surface of the single crystal silicon film, whereby the reduction of the gate dielectric strength can be prevented.
