Abstract: PURPOSE:To relax step difference of a semiconductor substrate wherein an element is formed and to simplify a manufacturing process by performing a process of ion implantation of metal to a region of well formation on a semiconductor substrate and a process for forming a selective oxide film in the region whereto ion implantation is carried out simultaneously with diffusion treatment at least once. CONSTITUTION:A process of ion implantation of metal to a region of well formation on a semiconductor substrate and a process for forming a selective oxide film in the region whereto ion implantation is carried out simultaneously with diffusion treatment are carried out at least once. Thereby, a region of well formation thereto ion implantation of metal is carried out is selectively oxidized, a surface of a semiconductor substrate is lowered as compared with other region by removing the oxide film by etching, etc., thereafter and step difference with a peripheral circuit can be relaxed even if a transistor, capacitor, etc., are formed by lamination in the region in a following process. If the two processes are performed twice, a nitride film which is used in the first selective oxide film formation can also be used in the following process; therefore, a manufacturing process can be simplified.

Title: Current detector
Inventor: KUROODO GUDERU
IPC: G01R19/00
Filed: 1988-10-17
Abstract: PURPOSE: To enhance the accuracy of measurement and high frequency characteristics by improving a magnetic circuit. CONSTITUTION: A main conductor 3 penetrates the inner cavity of a magnetic circuit 1 having an air gap 2 arranged with a magnetic detection element, i.e., a Hall element 5. A measuring coil 4 is disposed around magnetic circuit parts 7, 8 having the air gap 2. A yoke 6 serving as a magnetic shunt of the air gap 2 is arranged on a nonmagnetic coil case 9. The yoke 6 has length substantially equal to that of the coil 4. Flux generated from the main conductor 3 is canceled by a current flowing through the measuring coil 4 thus nullifying the flux in the air gap 2. Current flowing through the main conductor 3 can be detected from the current flowing through the measuring coil 4 at that time. Since the yoke 6 is arranged, accuracy of measurement is enhanced and the current can be detected with high accuracy up to a high frequency exceeding 100kHz.

Abstract: PROBLEM TO BE SOLVED: To enhance the accuracy of base line measurement by providing a mark plate with which the marks on a substrate and a mask can be detected simultaneously with a detecting system. SOLUTION: The amount of positional deviation between the index mark on an index plate and a reference mark FM1 in an off-axis alignment system is computed on a wafer. At the same time, the positional deviation between a reticle mark RM1 and a reference mark FM2, in the TTR alignment system of objective lenses 1A and 1B, is measured on the wafer side. The center coordinate position YIf in a Y-direction of a projected image is computed by having a wafer stage WST more and reticle mark RM1 scanned two-dimensionally with the use a light-emitting slit mark. At the same time, a Y-coordinate position YLS of the mark taken-in by laser step alignment(LSA) system is computed. The difference between the positions YLS and YIf is the amount of base line of the detected center part of a TTL alignment system by the LSA system in the Y-direction and the projected point of the center of a reticle R.

Filed: 1992-09-30
Abstract: PURPOSE:To position a recording paper accurately and automatically by calculating the position of the recording paper where a recording paper is to be located at present time and then feeding the recording paper to that position. CONSTITUTION:A CPU 8 recognizes a time-axis matching instruction when a switch 6 is pressed and rotates a pulse motor 2 by a speed instruction signal S1 and then feeds a recording paper 12 by fast forward. At the same time, an optical sensor 4 judges whether a specific mark indicating a reference time position corresponding to 0 hour is detected or not. The fast forward is stopped and the time difference between the current time recognized by a real-time clock 7 and the present time 0 hour on the recording paper is calculated. Based on the time difference and the deviation on the time axis between the position of a recording pen which is recorded previously and the 0 hour position, the amount of recording paper 12 to be further fed, namely the number of pulses D for alignment which is to be added to the motor 2 is calculated. When the number of pulses given to the motor 2 measured via a counter 5 after the fast forward is restarted matches the number of pulses D, the fast forwarding is stopped and a normal paper feed continues.
