Title: Semiconductor device and its manufacture
Inventor: AKIYAMA SHIGENOBU
IPC: H01L27/12
Filed: 1982-09-09
Abstract: PURPOSE:To improve controllability in case of the recrystallization of an island made of a semiconductor insulated and isolated through the irradiation of energy beams by repeatedly forming a pattern with fine unevenness previously on at least one end of the end sections of the island when the island is formed on an amorphous insulator substrate. CONSTITUTION:The surface of the Si substrate 30 is oxidized to form an SiO2 film 31, a polycrystalline Si layer 42 is deposited on the film 31, and the exposed section of the layer 42 is thinned until its thickness is halved approximately through etching while using a laminated film of a protective oxide film 50 and an Si3N4 film 51 as masks. The laminated film is removed, the layer 42, which is oxidized in steam atmosphere and thinned, is changed into an SiO2 film 31', and the layer 42 of original thickness after removing the laminated film is surrounded by the film 31', and insulated and isolated insularly. A continuous-wave Ar laser 52 is irradiated to the insular layer 42, and the layer 42 is melted, and solidified and changed into a single crystal, but laser beam spots 53 are irradiated to the end sections of the layer 42 at that time, and fine irregularities are generated in the end sections.

Filed: 1995-06-22
Abstract: PURPOSE: To provide a method for manufacturing a semiconductor device which can improve etching processibility on the upper substrate face having an element separation film. CONSTITUTION: An anti-oxidation pattern 14 formed on a substrate 11 is used to oxidize the substrate 11, and an element separation film 15 comprising an oxide film is formed on a surface of the substrate 11.

Title: Phase detection circuit, timing adjustment circuit and data discrimination circuit
Inventor: YAMAMOTO MICHIYO
IPC: H04L7/00
Filed: 1998-06-04
Abstract: PROBLEM TO BE SOLVED: To easily detect a phase difference between a data signal and a clock signal even for a super high-speed signal such as of a gigahertz band. SOLUTION: A data signal and a clock signal are inputted to a data input terminal D and a clock input terminal CK of a D flip-flop 22 respectively, a discrimination level shifted from an optimal discrimination level for the input data signal is given by a discrimination level generation part 21, and a DC level of the output of the D flip-flop 22 is detected by a DC level detection part 23. Thus, it is possible to detect a phase difference between the input data signal and an input clock signal without using a high speed circuit element higher than a signal to be processed without taking into consideration an output delay of the D flip-flop owing to change of an external condition such as temp./ power source fluctuation, or change of a delay amount owing to connection wiring.

Title: High-speed-interference distance measuring device
Inventor: SUZUKI NORITO
IPC: G01B9/02
Filed: 1984-07-26
Abstract: PURPOSE:To remove the speed limit, by judging the positive and negative values of an expression f1-(f2-DELTAf), where f1 and f2 are the frequencies of a two-frequency laser and DELTAf is the frequency shift due to doppler effect. CONSTITUTION:Light from a laser 1, which emits two polarized light beams, whose frequencies are different and which are crossed at right angles, is split into the first and second polarized light beams, whose frequencies are f1 and f2, by a poralizing beam 2. The first polarized light is reflected by a fixed reflecting mirror 3. The second polarized light is reflected by a moving reflecting mirror 4. Both light beams are overlapped by a beam splitter 5. The first polarized light passes a phase piece 6 and the phase is different by 90 deg.. Said first polarized beam is divided into two polarized beams, which are different by + or -45 deg. from the azimuth of the first polarized beam. When the first polarized beam is overlapped with the second polarized beam, the components of the second polarized light in the direction of phase advancing axis and the direction of the phase delaying axis of the phase piece interfere with the two components of the first polarized light. The polarized beams in the phase advancing direction and the phase delaying direction of the phase piece are separated by a polarized light beam splitter 8. The split beams are detected by detectors 10 and 11. Thus the optical beat based on the interference is obtained.

Title: Production of dielectric insulation isolated integrated circuit
Inventor: OKUHARA SHINJI
IPC: H01L21/31
Filed: 1979-12-04
Abstract: PURPOSE:To eliminate disconnection of the wiring with a thicker oxide film surrounding a diffused region by forming an oxidation inhibiting film on the region for heat treatment when a wiring is provided in the diffused region which is formed in a window etched through the oxide film applied on the semiconductor region such a manner as to extend onto the film. CONSTITUTION:An oxidation inhibiting film 7 made up of an Si3N4 or the like is formed on the surface of a monocrystalline semiconductor region 3 supported with a polycrystalline semiconductor 1 and surrounded by an oxide film 2 through the film 2. The film 2 is oxidized again to increase the thickness only in the part exposed to the surface with the part under the film 7 as intact. In this manner, the film 2 on the region adjacent to the film 7 is made thicker than the combined part of the film 2 and film 7. Then a window is made through the combined films to form a specified diffused region in the region 3 from which a wiring 4 is applied onto the film 7 and the thickened film 2. This facilitates the formation of two oxide films, thick and thin, eliminating any etching thereby simplifying the formation of the wiring free from disconnection.
