Title: Method of manufacturing semiconductor devices
Inventor: TSUCHIYA YOSHIKO
IPC: H01L27/092
Filed: 1996-04-22
Abstract: PROBLEM TO BE SOLVED: To make it possible to remove selectively WSix (Tungsten silicide) film, even on a narrow field oxide film, in order to prevent mutual diffusion of both impurity, P-type and N-type, contained in the W-polycide gate electrode of Dual Gate CMOS. SOLUTION: An area where nMOS is to be formed is covered by SiOx mask 12a and the second resist pattern 14(PR) being apart from its pattern edge by the distance of removal width Wrem is formed on an area where pMOS is to be formed. After n<+> -type area 10n is formed by making an ion implantation on a polysilicon film by applying the second PR14 as masking, the WSix film 11 is removed by the removal width Wrem by applying both patterns 12a and 14 as masking. The variation of the removal width Wrem depends on only the error Δd' caused by overlap of the second PR14 and a required forming width WFI of the field oxide film 4 is completed just by adding an overlap error of both patterns 12a and 14 to both areas of Wrem.

Abstract: PURPOSE:To obtain a semiconductor substrate and a semiconductor light receiving/emitting element which are superior in reliability and can be highly integrated by making a specified crystallographic axis of the crystal layer in a longitudinal direction of a rectangular semiconductor crystal layer. CONSTITUTION:An n-type GaAs layer 2 having a large thermal expansion coefficient, a buffer layer 3 which suppresses defects in a crystal, an n-type GaAs layer 4, an n-type GaAlAs cladding layer 5, a GaAs active layer 6, a p-type GaAlAs cladding layer 7 and a high concentration p-type GaAs cap layer 8 are formed in that order on an n-type (001) orientation Si substrate 1. A longitudinal direction of the substrate is processed into a stripe and a rectangular island having a width of 5mum or thereabouts along a <100> crystal orientation by chemical etching. To compensate for stress to a greater extent, an SiO2 layer 9 is formed while an interval having a width of a little under 5mum is left, thereby constituting an electrode 10. Hence, stress which accounts for performance deterioration is reduced, and it is possible to produce a light receiving/emitting element with a superior reliability which can be highly integrated.

Abstract: PURPOSE:To prevent a floating capacity existing behind an inter-polar voltage detecting device from being connected between poles and enable a highly accurate electric discharge machining by using an insulation amplifying device in a rectifying circuit input part and carrying out insulation between the part across the poles and said inter-polar voltage detecting device. CONSTITUTION:An AC voltage between poles 2 from an AC power source 1 is applied to current restricting resistors 4, 5 by a detecting line 3, and insulated from the following circuits by means of an insulation transformer 14 which is connected between the resistors 4, 5. Its secondary side voltage is converted into a pulsating current through a rectifying circuit 6, turned into a DC voltage through a dummy resistor 14 and a smoothing circuit 7 of a capacitor, etc., and inputted into an NC control unit 9 from an A/D converter 8. Accordingly, floating capacities 12, 13 existing at various parts behind the transformer 14 are not connected to between the poles 2 and, when a floating capacity 10 is reduced by changing the connection between the poles 2, a discharge current with a small current peak value and pulse width can be obtained, improving a surface roughness. Also, since the condition across poles can also be detected, control can be made in accordance with the condition between the poles.

Title: Magnetic head
Inventor: MATSUSHITA YUMI
IPC: G11B5/133
Filed: 1988-04-25
Abstract: PURPOSE:To eliminate the need for forming an artificial gap and, in addition, to obtain a sufficient reproduced output by directly butting the joining surface of a nonmagnetic core joined with a body having a high saturated magnetic flux density on the other side against a body having a high saturate magnetic flux body and integrating them to one body after the joining surface is inclined. CONSTITUTION:A nonmagnetic core 10 and a body 11 having a high saturated magnetic flux density are directly butted against each other and integrated to one body and the joined body is joined with a ferromagnetic core 12 with adhesive glass 14 buried in track grooves 13 controlling a track width Tw and a gap spacer thin film 16 adhered to the upper end section between the track grooves 13 forming a magnetic gap 15 only. Since the joining boundary surface between the nonmagnetic core 10 and body 11 having the high saturated magnetic flux density brought closer to the magnetic gap 15 is not the joining boundary surface between magnetic bodies, the magnetic gap does not become an artificial gap and no noise is produced. Moreover, since the cross-sectional area of the body having the high saturated magnetic flux density is large against the closed magnetic path of a central leg section 17 with wound coil, the magnetic reluctance can be lowered sufficiently and, therefore, a sufficient reproduced output can be obtained.
