Title: Manufacture of semiconductor device
Inventor: TANAKA YOSHINORI
IPC: H01L21/76
Filed: 1988-07-01
Abstract: PURPOSE:To precisely form a diffusion layer using the self-alignment technique by a method wherein a second conductor film is formed on the side-walls of a laminate of a first and second insulating films and a first conductor film through the intermediary of a third insulating film and then an impurity same as a semiconductor substrate in conductivity type is caused to be diffused from the second conductor film into the semiconductor substrate. CONSTITUTION:On the surface of a silicon substrate 1, an insulating film 2, a conductor film 3, and an insulating film 4 are formed. An oxide film 6 is formed on the surface where the silicon is exposed, and the oxide film 6 is retained on the sidewalls of the three-film laminate. A polycrystalline silicon layer doped overall with boron is deposited. The polycrystalline silicon layer is subjected to anisotropic etching and a sidewall 7 is formed on the patterned three-layer laminate. Next, heat treatment is accomplished for the formation of an insulating film 8 on the surface of the sidewall 7 and on the surface of element forming regions 10 on both sides thereof. Simultaneously, with boron being diffused from the sidewall 7 into the substrate 1, a P<+> inversion preventive layer 9 is formed by self-alignment. This method results in the inversion preventive layer 9 positioned just under the element isolation region, realizing excellent isolation characteristics.

Title: Polishing device
Inventor: HAMAGUCHI TSUNEO
IPC: B24B37/07
Filed: 1983-09-08
Abstract: PURPOSE:To polish a workpiece to have a strain-less mirror surface by providing a means for applying a certain force to a support plate in the direction of separating from a polishing plate and immersing the workpiece in polishing liquid. CONSTITUTION:A support plate 2 for holding a workpiece 1 is secured fixedly to a flange 4 the other end of which is connected to a piston 5. The piston 5 together with a weight 6 constitutes a U-shaped pipe 8 through fluid 7 to apply a certain force in the direction of arrow 9. Also, the workpiece 1 is immersed in polishing liquid 11 filling a tank 10. When a polishing plate 12 is rotated in the direction of arrow 13, the relative speed is produced between the plate 12 and the workpiece 1 and flow of the liquid 11 is produced in a gap 14 between the workpiece 1 and the plate 12. When the relative speed is increased, pressure in the gap 14 is reduced to lessen the gap 14. And when the rotation of the plate 12 is stopped, the relative speed between the workpiece 1 and the plate 12 is lost. Thus, the workpiece can be polished to have the strain-less mirror surface.

Abstract: PURPOSE:To give a mechanism serving as a robot arm to a transport vehicle by shifting a mounting bed section for holding respective sensors and conveyer members between production facilities so as to lift the mounting bed section relatively to a movable car body according to the height of a carrying-in and -out port provided between the movable car body and mounting bed section. CONSTITUTION:A transport vehicle 1 having workpieces W2 previously mounted thereon is shifted to a device A along a guiding conductor 5 and stopped by a guide path detecting sensor SF according to a travelling control display mask m1. Next, the height of a carrying-in and -out port of the device A is judged by a distance sensor S1 to locate a mounting bed 2 to the height of the device A according to the judgement. When the workpiece w1 on the device A is pushed out to the mounting bed section 2 to be stacked, the transport vehicle 1 is shifted to a device B. When the transport vehicle 1 arrives at the device B, it is driven by a distance sensor S2 until the mounting bed section 2 and the carrying-in and -out port of the device B have the same heights, so that the transportation can be carried out without needing a robot arm.

Title: Frequency discrimination circuit
Inventor: ISHII SHIGENORI
IPC: G01R23/15
Filed: 1987-07-06
Abstract: PURPOSE:To perform discrimination accurately and in a short time by setting an error limit value corresponding to frequency set to frequency setting part and to compare this error limit value with the count value to perform operation of discrimination signal. CONSTITUTION:In an operation processing means 5 of frequency discrimination circuit, a latch signal for suppressing operation processing which is output from a timer 4 allows a comparator 5c to be latched. The latch of the comparator 5c is released when the measuring time ends and the timer 4 is exceeded. At this time, if the count value of error pulses output from an error counter 5b is greater than the limit value output from a decoder 5a of count value of error pulses, a discrimination signal is obtained, indicating that a signal which is different from the frequency set from the comparator 5c is being input. Thus, this discrimination signal allows discrimination accurately and in a short time.

Abstract: PURPOSE: To supply always a constant amt. of a gas flux despite the change in the storage amt. of the flux by atomizing the liquid flux in a tank on siphon principle by a gas of constant pressure, mixing this with the gas in a bypass pipe and supplying the mixed gases.  
     CONSTITUTION: The LPG from a gas source in flctuating of pressures is reduced to constant pressure, and is branched through a supply pipe 8 into a bypass pipe 14 and a gas lead-in pipe. The latter gas is further reduced to constant  pressure with a regulator 6 to decrease the pressure fluctuations exerted upon  the inside of a tank 1 and is ejected to a gasl layer part through an ejection  port 9. A liquid flux 2 is gasified by a blow-up pipe 10 and while the amt.  thereof is controlled, it goes through a lead-out pipe 5 into a mixer 12. Here,  the gaseous LPG is stably supplied from the pipes 8, 14 and therefore the flux  is supplied in the constant pressure and constant volume state through a supply  pipe 13 into a brazing part (burner part).
