Title: Gettering method for semiconductor device
Inventor: AOKI YASUO
IPC: H01L21/322
Filed: 1987-01-27
Abstract: PURPOSE:To perform intense gettering of contaminants attached to the active region of a semiconductor substrate, defects and the like without dispersion, by uniformly forming gettering sites in the region other than the active regions of the semiconductor device on the surface of a substrate. CONSTITUTION:A substrate is thermally oxidized and a thermal oxide film 102 is formed. Thereafter, patterning is performed so as to mask a semiconductor-device forming region 101 with a masking material 103 such as photoresist. Then, the thermal oxide film is etched, and semiconductor-device isolating regions 201 are exposed. Thereafter ions of argon 202 are implanted. Finally, the masking material is removed, and heat treatment at the time of manufacturing the semiconductor device is performed. Then gettering sites 302 are formed in the semiconductor-device isolating regions in the substrate 301. The method for forming the gettering sites from regions other than active regions 501 of the semiconductor device is the same when the gettering sites are introduced in the semiconductor-device isolating regions.

Title: Formation of thin film
Inventor: SHIOTANI YOSHIMI
IPC: H01L21/205
Filed: 1988-01-28
Abstract: PURPOSE:To form a thin uniform film and to inhibit the occurrence of pinholes in a film by supplying plural reactant gases alternately and intermittently onto a substrate and then forming a thin film on the substrate by a vapor growth method. CONSTITUTION:Reactant gases (e.g., NH3 and SiH2Cl2) are introduced through inlet holes 2, 3, respectively, into a reaction chamber 1 and the inside of this chamber 1 is evacuated through an outlet 4, by which the inside of the chamber is maintained at the prescribed gas pressure. Subsequently, the reaction chamber 1 is heated from outside by means of a heater 5, by which the reactant gases are subjected to thermal decomposition and a thin film (Si3N4) is formed on a substrate 6. At this time, respective reactant gases (NH3 and SiH2Cl2) are alternately and intermittently supplied onto the substrate 6 and film formation is carried out while accurately controlling timing. By this method, film-thickness distribution can be improved and a thin film free from pinholes can be obtained.

Title: Duty control voltage generating device for automatic transmission
Inventor: KATO YUJI
IPC: F16H59/72
Filed: 1985-02-01
Abstract: PURPOSE:To calculate duty corresponding to a command duty control voltage accurately all the time even during variation in driving voltage and to hold a duty control voltage invariably at the command by correcting the driving duty of a solenoid according to the variation in driving voltage detected by a sensor. CONSTITUTION:A microcomputer 101 inputs the signal from an engine rotating speed sensor 14, the signal from a throttle opening extent sensor 15, the signal from a gear position sensor 16, the signal from a voltage sensor 17 which detects the driving voltage V of the solenoid 18 for generating the duty control voltage, and the signal from a oil temperature sensor 16 which detects the oil temperature T of an automatic transmission, thereby performing duty control over the solenoid 18 with output duty D based upon the arithmetic result of those signals. The solenoid 18 generates the command duty control voltage securely by correcting the duty in such a state that the duty control voltage deviates from the command owing to variation in the driving voltage V and performs the control accurately without any variance even during voltage variation.

Title: Diagnostic method
Inventor: SATO YOSHIO
IPC: G06F11/22
Filed: 1987-01-30
Abstract: PURPOSE:To automatically form logical planning with no regard to a logical restriction item and a diagnostic data of a high detection rate, by providing logic for facilitating diagnosis in an FF cell and avoiding logical restriction infringement logic. CONSTITUTION:When a diagnosis exclusive pulse signal M.C1 is sent out to FFB in place of a system clock Tn, the value 1 of FFA on the side of a salve 21 thereof is taken in FFB on the side of a master 20. At this time, M.C1 is also sent out to FFA and the D-input value of FFA is taken in FFA on the side of the master 20. However, this change is blocked on the side of the slave 21 of a post stage and is not propagated to FFB. Next, the transmission of a value from the side of the master 20 to the side of the slave 21 is generated in FFB by a diagnosis exclusive signal C2 (pulse). At this time, C2 is also sent out to FFA and the transmission of a value from the side of the master 20 to the side of the slave 21 is generated. In this sequence, the M.C1 pulse becomes a 0-level and the change in the output of FFA generated at a pulse falling point is not takken in FFB and, therefore, FFB holds the value held by FFA.

Title: Dc-dc converter control circuit
Inventor: KITAGAWA KIYONARI
IPC: H02M3/158
Filed: 1998-01-30
Abstract: PROBLEM TO BE SOLVED: To prevent the output voltage of a DC-DC converter from vibrating by forcibly turning off a transistor for synchronous rectification for a certain amount of time when the DC-DC converter is started. SOLUTION: A reference voltage Vref and a soft start voltage Vss to be inputted to an amplifier(AMP) 20 are inputted to a comparator(COMP) 27. The comparator(COMP) 27 outputs H when a DC-DC comparator is started, namely while a soft start voltage Vss is smaller than a reference voltage Vref, sets the output of a driver (DV2) 26 to L, and turns off a synchronous rectification transistor (Q2) 8. As a result, the loop of a resonance current through a smoothing reactor (L1) 4, a smoothing capacitor (C1) 6, and a transistor (Q2) for synchronous rectification is broken for a certain amount of time after starting even if overshooting occurs in the output voltage of the amplifier(AMP) 20, thus preventing the output voltage of the DC-DC converter from vibrating.
