Title: Semiconductor laser device
Inventor: NAKATSUKA SHINICHI
IPC: H01S5/00
Filed: 1984-04-20
Abstract: PURPOSE:To prevent any leakage current due to unmatched P-N junction between burying and buried layer as well as any defective burying due to liquid- growth on (GaAl)As from happening by a method wherein a burying layer is selfmatchingly isolated by impurity diffusion while MOCVD process or NBE process suitable for acceptable crystal growth on (GaAl)As is applied for burying growth. CONSTITUTION:Layers 18, 19, 20, 21, 22, 23 are crystal-grown on an N type GaAs substrate 17 by MOCVD process. This composition is etched utilizing an SiO2 layer as a mask to perform burying growth with SiO2 film left as it is. Before the crystal growth in case of burying growth, dimethyl zinc as P type dopant gas and AsH3 for preventing As loss are introduced into reaction system for Zn diffusion. After forming a Ga0.55Al0.45As (P=1X10<18>cm<-3>, 0.5mum) P type inversion layer 24, this layer 24 is filled with N type Ga0.55Al0.45As 25 and polycrystalline (GaAl)As adhered to SiO2 is removed by lift off process. An N<+> (GaAl)As layer 20 only is left as N type by Zn diffusion before burying growth. This composition may be filled with N type Ga0.55Al0.45As.

IPC: G11B20/18
Filed: 1993-03-15
Abstract: PURPOSE:To efficiently record and reproduce data by using one of ECC circuits as an ECC coding circuit for writing-in information and the other ECC circuit as an ECC decoding circuit for detecting errors of reading-out information at the time of recording operation, and using both ECC circuits as the ECC decoding circuit at the time of reproducing operation. CONSTITUTION:In recording operation, this information is read by an optical disk drive 7 immediately after writing for a real time RAW check of recording information, transferred to an ECC circuit 4 via a demodulation circuit 6, and detection processing for errors is performed. A control circuit 11 performs rerecording or alternation processing from results of the RAW check according to the following way. That is, if the number of errors are less than allowable numbers, writing is made normal, and if it exceeds allowable numbers, writing is made abnormal. Next, in a switching state of a switch at the time of reproducing a control circuit 11 makes the ECC circuit 3 and the ECC circuit 4 function as a ECC composite circuit when a host device 1 issues a reproducing instruction, and switches an input of a switch 8 to a (a) side, an input of a switch 9 to a (d) side, and an input of a switch 10 to a (f) side.

Filed: 1994-04-18
Abstract: PURPOSE:To provide a method for enhancing measurement accuracy of a work position by a simple method. CONSTITUTION:Facfors to decrease a photodetecting quantity, such as stains, rust, discoloration and flaws, lead to a degradation in the measurement accuracy when such factors arise at the surface in the measurement position of a weld zone in measuring the position of the weld zone of two objects a and B by using an optical sensor. The reflected light quantity of the surface part of the measurement position is required to be improved in order to improve the measurement accuracy by removing such factors to degrade the measurement accuracy. A coated part is constituted by executing coating application with a spray 2 in the peripheral part 1 of the surface in the measurement position in order to improve the reflected light quantity. The stains, rust, discoloration, flaws, etc., produced by welding, etc., are repaired by constituting the coated part in the peripheral part 1 of the surface in the measurement position. The light reflection efficiency is enhanced in the part where the light reflection efficiency of the surface part in the measurement position is degraded by the welding, etc., according to the repair by such coating. The improvement in the light reflectivity facilitates the detection of the end of the object to be measured.

IPC: C22C19/05
Filed: 1981-05-25
Abstract: PURPOSE: To enhance the melt sticking resistance of an Ag-Ni electrical contact material without deteriorating the advantages of the Ag-Ni alloy by adding W, Cr or Mo to the contact material.  
     CONSTITUTION: An electrical contact material made of alloy consisting of 40W 60wt% Ni, 0.5W5% of ≥1 kind of element selected from W, Cr and Mo, and the balance Ag is provided with enhanced contact performance by uniformly dispersing W, Cr and Mo in an alloy material so as to prevent the aggregation of Ni, and high workability, stable contact resistance and superior hardly dissipative property which are advantages of an Ag-Ni electrical contact material are not deteriorated. In the composition <40% Ni results in insufficient melt sticking resistance, and when the Ni content exceeds 60%, Ni is oxidized to increase  the contact resistance. When the total amount of W, Cr and Mo is <0.5%, the  aggregation of Ni due to arc heat of a contact can not be prevented, and >5% W, Cr and Mo deteriorate the workability and cause remarkable dissipation.

Title: Manufacture of semiconductor device
Inventor: SUZUKI SHINICHI
IPC: H01L21/76
Filed: 1994-04-18
Abstract: PURPOSE:To easily and accurately flatten a semiconductor substrate surface having an element isolation structure with thermal oxidation isolation and U-groove isolation combined. CONSTITUTION:A thermally oxidized film 3 is formed on a semiconductor substrate 1, and a U-groove 7 is formed therein. The U-groove 7 is filled with a silicon oxide film 8 as an insulator, so that an element isolation structure with thermal oxidation structure and U-groove isolation combined is formed. A semiconductor wafer formed with this element isolation structure is subjected to polishing for flattening. Therefore, a 'recess' which has occurred at a center of a conventional U-groove structure is eliminated, so that an excessive conductor (polysilicon) may not remain in this 'recess' at the time of patterning a wiring layer for avoiding short-circuiting. In addition, since no stage exists on a surface of a semiconductor base 10, exposure accuracy in a manufacturing process may be improved, while since an amount of over-etching is reduced, machining accuracy of a wiring pattern may be improved for realizing high integration of an LSI.
