Title: Manufacture of semiconductor device
Inventor: SHIGEMATSU YASUHIRO
IPC: H01L21/3205
Filed: 1987-05-18
Abstract: PURPOSE:To complete the flatness of a semiconductor device by patterning recesses on the surface of an insulating film, then forming a conductor film by invading it into the recesses, forming a coating film on the conductor film, temporarily flattening it, retaining wirings in the recesses, and removing by etching the conductor film and the coating film. CONSTITUTION:A photoresist layer is formed on an insulating film 2, and a photomask is placed from above to expose the layer. After the layer is developed, recesses 3 are formed on the film 2 by etching an Si substrate 1. Then an aluminum film, a conductor film 4 and a coating film 5 are superposed on the film 2. Then, since the surface of the film 4 is depressed at parts directly above the recesses 3, the film 5 made of resin or photoresist is formed to be flattened, and the films 4, 5 are removed by dry etching. Then, wirings 8 are formed on an upper layer insulating film 7 formed on wirings 6. Thus, a complete flattening is conducted to easily form a plurality of wiring layers.

Abstract: PURPOSE:To actually prevent machining errors by setting a machining prohibition area of a machine tool in a program independent of a machining program of the machine tool, and setting a movement prohibition area with a specified clearance relative to the machining prohibition area. CONSTITUTION:Considering the fact that a tool always has a tip radius R and that the amount of a clearance K is as small as 0.01-0.5 mm, a machining prohibition area 41 is defined to be equal to the drawing shape of a work, and the clearance alpha is set by checking with a tip circle 43 of a soft template check system with a correction of a tool tip 42 only. To obtain the edge tip point which is a point on a tool circumference, the equation I is used where R is the radius of the tool edge radius, and theta is the division angle of the arc of the tool edge radius R (assuming the number of division to be n, theta = 2 pi/n). In this way, a machine tool operation is stopped when the coordinates of the tool edge point obtained as described above enters a movement prohibition area having a clearance alpha.

Title: Cr timer with variable set time
Inventor: MATSUMOTO SHINGO
IPC: H03K17/28
Filed: 1981-08-05
Abstract: PURPOSE:To eliminate a difference between timer time and a scale even if the value of a variable resistance for setting the timer time has an error, by varying a threshold voltage to be applied to a timer IC. CONSTITUTION:When a trigger pulse is applied to the trigger signal input terminal TR of a timer IC1, charging to a capacitor C is started through a variable resistance VR and the terminal voltage of the capacitor C rises according to an expontentional function. When the resistance value of the resistance VR is greater than a designed value, the time constant increases, so that time T1 up to when the terminal voltage reaches a threshold voltage VTh becomes longer than timer time T0. When less, the time T2 up to when the voltage reaches the voltage VTh becomes shorter than the time T0. In this case, a variable resistance VRt for threshold voltage adjustment is adjusted according to the value of the resistance VR to increase or decrease the value of the voltage VTh to be applied to a threshold voltage terminal Th.
