Title: Method for jointing crystalline substrates having different crystal lattices
Inventor: LEVINE BARRY F
IPC: H01L31/04
Filed: 1998-10-08
Abstract: PROBLEM TO BE SOLVED: To joint substrates different in crystal lattices by forming a layer of a material, having specified thickness on a first substrate in first and second substrates which differ in crystal lattices. SOLUTION: A device 200 is formed on an n+ silicon substrate 205. The device 200 is formed of deposition to which the pattern of a material 210 is given. A layer 220 of InGaAs and a layer 225 of InP are formed on an InP substrate. An InP/InGaAs substrate is placed in a silicon MBE chamber, and a silicon layer 215 having the thickness of a range from 1 nm to 2 nm is grown on the surface of InGaAs 220. Thus, defects due to the non-matching of the lattices is controlled. A substrate covered with Si and the silicon substrate 205 are placed on a container, which compressively bonds them in a device where the substrate is connected to the silicon substrate 205. When the substrate is heated at about 450-700 deg.C in H gas while it is placed under pressure, the substrate differing in the crystal lattices can be connected.

Filed: 1999-10-06
Abstract: PROBLEM TO BE SOLVED: To provide a system for predicting quality and controlling process where polymerization reaction is carried out in a batchwise polymerization autoclave, capable of highly uniformly maintaining product quality even when variable factors exist in environmental conditions, raw materials and reaction equipment. SOLUTION: In this system for predicting quality and controlling reaction, a simulation unit 104 simulates product quality at a constant period by using a process model and process data resulting from measuring the process 101 where the polymerization reaction is carried out in the batchwise polymerization autoclave, and simultaneously corrects the process model. A predication and judgment unit 110 judges whether the simulated and predicted product quality deviates from a permissible tolerance of the quality or dose not. When the product quality is judged to deviate, a correction and operation unit 111 determines a correctional operation to be applied to the process and most suitable operational variables for the operation after predicting the result which will be brought about by the correctional operation through the simulation.  The determined correctional operation and the most suitable operational variables are supplied as output data to a general-purpose control system 102 so as to control the polymerization reaction of the process 101.

Filed: 1987-11-13
Abstract: PURPOSE:To shorten the installation time of a disk by writing latest fault control information on a band to which a designated address belongs into a memory after the instruction of an access to the designated address is received at the time of recording or reading information. CONSTITUTION:A processor firstly checks to which band the address designated by a host computer 6 belongs based on having read control track information.
