Title: Manufacture of lddmos transistor
Inventor: OHIRA MASAAKI
IPC: H01L29/78
Filed: 1988-10-21
Abstract: PURPOSE:To stabilize the depth of a low concentration impurity layer, and prevent impurity from diffusing into a shallow diffusion part by a method wherein, after an excessive silicon layer is formed on a substrate surface before ion implantation of impurity for LDD, and a silica coating film is formed on a gate polysilicon layer surface, a side wall is formed on the side surface by etching back. CONSTITUTION:On an N-well layer 1 surface of a semiconductor substrate surface, a silicon oxide film 2 and a gate polysilicon layer 3 are selectively formed; by using the gate polysilicon layer 3 as a mask, ion is implanted in the surface of the N-well layer 1, thereby forming an excessive silicon layer 4 of the N-well layer 1. After that, ion is implanted into the excessive silicon layer 4, and a low concentration boron layer 5 is formed. A silicon oxide film 6 grown by thermal decomposition of organic oxirane, and a silica coating film 7 are heat-treated and etched back, thereby forming a rigid side wall 10 on the side surface of the gate polysilicon layer 3. By this set-up, the depth of a low concentration impurity layer is stabilized, and boron in a high concentration boron layer 8 is prevented from diffusing into the shallow diffusion part of an LDD(lightly doped drain) part.

Title: Production of magnetic recording medium
Inventor: SHINOHARA KOICHI
IPC: G11B5/725
Filed: 1986-11-10
Abstract: PURPOSE:To improve durability and weatherability by disposing a lubricating agent by a soln. coating method on a thin ferromagnetic metallic film disposed on a high-polymer film, then subjecting the coating to an ozone treatment. CONSTITUTION:The thin ferromagnetic metallic film is disposed on the high- polymer film which is a substrate 1 to be treated and the lubricating agent is disposed by the soln. coating method thereon. The soln. coating method is executed by dissolving the lubricating agent into a solvent, coating the soln. thereof by a reverse roll coater, bar coater, etc. on the film and drying the coating. An electron beam is accelerated from an electron beam generator 7 in an ozone treatment vessel 6 and the ozone is taken out of titanium foil or the like into the atm. and is produced from the oxygen in the air, by which the coating is treated. The reaction between the lubricating agent and the thin ferromagnetic metallic film progresses so that said agent and film stick strongly. The part in the thin ferromagnetic metallic film where the degree of oxidation is weak is reinforced by such adhesion plus the oxidation effect of the ozone. The use of the medium at and under the high temp. and high humidity is thereby permitted and the preservable characteristic is improved.

Title: Color filter
Inventor: ARIGA SHUJI
IPC: G02B5/20
Filed: 1984-12-18
Abstract: PURPOSE:To obtain a color filter having substantial durability against a heat treatment stage of high temp., thermal impact, etc. by providing transparent resin films (org. buffer layers) having the coefft. of thermal expansion equal approximately to the coefft. of thermal expansion of the transparent org. resin layers to the boundaries between a base and org. colored layers. CONSTITUTION:The colored layers 7, 8, 9 are all made into the construction in which all the layers are sandwiched by the org. resin layers if the org. buffer layer 2 is provided on the base 1. More specifically, the layer 7 is sandwiched by the org. buffer layer on the lower side and an intermediate layer 3 on the upper side. The layer 8 is sandwiched by the intermediate layers 3, 4 on the upper and lower sides respectively. The layer 9 is sandwiched by a protective layer 9 and the intermediate layer 4 on the upper and lower side respectively. The equal thermal expansion and thermal shrinkage are repeated at the upper and lower boundaries of the colored layers if all of the org. buffer layer 2, the intermediate layers 3, 4 and the protective layer 5 are constituted of the org. films having the equal coefft. of thermal expansion, e.g., if said layers are constituted on the org. films having the resembling structures. The thermal stress acting only in one direction on the layers 7, 8, 9 is therefore eliminated even if the color filter is subjected to the heat treatment, thermal shock, etc. The filter is thus kept free from cracking, peeling, etc.

Abstract: PROBLEM TO BE SOLVED: To suppress the delay at a high-frequency region by adding an error waveform pattern between an inverter output waveform this time and a desired cycle waveform to a previous inverter drive waveform pattern and updating an inverter drive waveform pattern. SOLUTION: A high-frequency PWM inverter control part 22 inputs an inverter output IO to a subtraction part 26a of an error signal generation part 26 and forms an error signal also from a sinusoidal wave reference signal which is inputted in synchronization with a system synchronization signal R. Then, an error amplification part 26b generates an error amplification signal E for the error signal, outputs it to a first low-pass filter 27, eliminates the high harmonics of the error amplification signal E, and outputs an output (f). An error waveform integral part 28 adds the output (f) of the first low-pass filter 27 and an inverter drive waveform pattern (g) at a previous cycle period at an addition part 28a, thus updating an inverter drive waveform pattern (p) and hence correcting delay by performing phase-advance processing at the addition part 28a.

Title: Optical recording medium
Inventor: ITO MASAKI
IPC: G11B7/24062
Filed: 1985-11-27
Abstract: PURPOSE:To obtain an optical recording medium high in servo stability and high signal quality by providing a reflecting film which is substantially transparent to the reading light between a substrate and a recording layer and setting the incident reflection factor of the substrate at a prescribed percentage or larger when a recording film is removed. CONSTITUTION:A recording layer 2 is formed on a substrate 1 and the recording laser light 3 is condensed on the layer 2 through the substrate 1. Thus a pit 4 is formed. Here a transparent reflecting film 5 is provided between the substrate 1 and the layer 2. The reflection factor is set at >=15%, for example, if no recording layer exists. This prevents the deterioration of the servo stability even after recording. Here the film 5 uses a material, e.g., SiO, ZnO, etc. that have a larger refractive index than that of the substrate 1. Thus the servo stability is secured for production of an optical recording medium high in quality.
