Title: Manufacture of semiconductor device
Inventor: SHIMIZU ATSUO
IPC: H01L29/78
Filed: 1987-11-12
Abstract: PURPOSE:To form in a self-alignment a silicon single crystal substrate surface with a high etching selection ratio by forming on the silicon substrate surface a four-layer pattern yielded by alternately superimposing SiO2 layers and Si3N4 layers and employing in place them as an etching mask and an oxidation- resistant mask. CONSTITUTION:An exposed surface of a silicon single crystal substrate 1 is oxidized using Si3N4 layers 24, 26 as masks to form an isolation insulating layer 28 composed of SiO2 around an intrinsic base region 40. Typically, the tip end of the isolation insulating layer 28 extends through the lower part of the Si3N4 layer 26 to the intrinsic base region 40 to from the so-called bird beak. Although a polycrystalline silicon layer 31 is grown on the isolation insulating layer 28, no silicon layer is formed on the SiO2 layer 23. The selective growth of the silicon layer is produced because doped Si<+> 30 is produced as a seed. A single crystal silicon layer 32 is grown from the side of a protrusion 41 byordibary epitaxial growth. Thus, a structure is obtained where the polycrystalline silicon layer 31 for constructing a lead electrode of the intrinsic base makes contact with the side of the protrusion 41 constituting the intrinsic base.

As a result, a signal (f) is inputted in the circuit 24. The signal (f) becomes the high level when the error is not detected and becomes the low level when the error is detected. The circuit 24 receives the signals (d) and (f), transmits a signal (g) when errors do not exist in the both signals and loads data (h) to a memory 16. The error correction in the prefix estimation when a decoding failes is performed by replacing the prefix value stored within a prefix circuit 28 by the prefix of failed data.

Title: Method for manufacturing hydrocarbon derivative
Inventor: RAMAKURISHIYUNAN RAMASHIYANDOR
IPC: C07C17/10
Filed: 1991-10-31
Abstract: A hydrocarbon derivative is produced by the vapour phase reaction of a hydrocarbon with substantially pure oxygen in the presence of a suitable catalyst in a reactor 2. The product is removed in a scrubber 8, carbon monoxide, present in the reactor effluent as a by-product, is oxidised to carbon dioxide in a converter 16 and part of the gaseous effluent, comprising mainly carbon dioxide and unreacted hydrocarbon, is recycled to the reactor 2. Removal of carbon monoxide from the recycle stream reduces the hazard of a fire or explosion in the reactor or associated equipment. The use of carbon dioxide as the principal diluent increases heat removal from the reactor, thereby increasing the production capacity of the reactor. If the hydrocarbon is benzene or a straight chain C4 hydrocarbon, e.g. butane, the product is maleic anhydride. If the hydrocarbon is o-xylene the product is phthalic anhydride. Other derivatives such as acetaldehyde, acrolein, acrylonitrile, methacrylonitrile, acrylic acid, vinyl chloride, and propylene oxide may alternatively be produced by appropriate selection of reactants and catalysts. <IMAGE>
