Title: Element isolation of semiconductor device
Inventor: TEJIMA AKITOMO
IPC: H01L21/76
Filed: 1986-02-06
Abstract: PURPOSE:To obtain a semiconductor integrated circuit having preferable characteristics by forming an element separating groove on a crystal defective region of a boundary between an insulating layer and a semiconductor layer and conducting oxidation or by forming dielectric isolation layers only by an oxidation process. CONSTITUTION:An Si3N4 film 11 is laminated by an SOEGI substrate, and an element isolation groove region 12 is opened by pattering. Then, an isolation groove 13 which arrives at a spinel layer 2 is opened by wet etching using an HF-CH3COOH-HNO3 solution. The depth of the groove is stopped on the spinel layer by this etching, but the etching is extended laterally along the crystal defective layer to form overhand shapes of an Si-SPE layer 6. Then, an oxide film is progressively grown on the side wall of the groove 13 by the thermal oxidation at 1,000 deg.C with wet O2 gas, grown in the shape of burying the groove, a crystal defective layer 17 existed on the boundary among the layer 2, a seed layer 4 and the layer 6 is progressively oxidized to form an SiO2 film 15 surrounding an island region 14 made of Si single crystal. The film 11 is eventually removed and the process is completed.

Title: Packet signal processor
Inventor: TACHIBANA TETSUO
Filed: 1987-02-05
Abstract: PURPOSE:To improve the throughput of a processor by allowing the processor to access a data transfer memory through a processor bus independently of the occupation of a packet signal data transmitting bus. CONSTITUTION:A packet signal received by a transmitting/receiving circuit 16 is stored in a data transfer memory 18 through a bus 19. The processor 17 accesses the memory 18 through a bus 20.

Title: Method of assembling semiconductor device
Inventor: TSUMORI MASAHIKO
IPC: H01L21/50
Filed: 1986-02-06
Abstract: PURPOSE:To reduce a thermal stress due to a different in linear expansion coefficients between a chip and a lead frame and to protect a semiconductor chip from breakage, by heating the semiconductor chip fixed to the lead frame during die bonding, wire bonding and molding processes. CONSTITUTION:A semiconductor chip 5 is heated to 300-400 deg.C while it is die bonded on a die bonder 2. Since a temperature of magazines 7 is held at about 300 deg.C while the chip 5 secured to a lead frame 6 is conveyed to a wire bonder 3, the semiconductor chip 5 is no subjected to thermal stress due to any difference in linear expansion coefficients between the chip and the lead frame. While a gold wire is connected to the chip 5 by means of the wire bonder 3, the chip 5 and the lead frame 6 are held at a high temperature of 250-300 deg.C. The chip 5 having the gold wire connected thereto is received in another magazine 7 whose temperature is held at abnout 200 deg.C and conveyed to a molding apparatus 4. Within the molding apparatus 4, the chip 5 is sealed with resin 8 having a temperature of 170-180 deg.C. Accordingly, a thermal stress F1 due to a difference in linear expansion coefficients between the chip 5 and the lead frame 6 is partially cancelled by a compressing force F2 by shrinkage of the resin 8.

Abstract: PURPOSE:To expand a capture range substantially by operating this PLL circuit so that the difference of frequencies between a demodulation clock and a data string signal is decreased when the difference between the frequency of the data string signal and the frequency of the demodulation clock is at the outside of the capture range of the PLL circuit. CONSTITUTION:When the difference of a frequency of a data string signal 101 and the frequency of a demodulation clock 112 is at the outside of a frequency pulling-in range (capture range) of the PLL circuit, a frequency comparator 103 detects it. Then the difference of the frequency of the data string signal 101 and the frequency of the demodulation clock 112 is within the frequency pulling-in range (capture range) of the PLL circuit by applying frequency pulling-in operation of the frequency comparator 103. Thus, the frequency pulling-in range is substantially expanded.

Filed: 1993-01-21
Abstract: PURPOSE:To produce the subject product excellent in the surface slippage without impairing its physical properties or its visual appearance by dispersing tribasic calcium phosphate in film according to a specified method and forming fine projections on the film surface. CONSTITUTION:A suspension of tribasic calcium phosphate dispersed in water is initially dispersed in an organic polar solvent (preferably N,N- dimethylformamide, etc.) and the resultant dispersion is subsequently dehydrated preferably using zeolite as a dehydrating agent.
