Patent JP-S59117829-A (JP)
Title: Phase locked circuit
Inventor: NAKAMURA HIDEKI
IPC: H03L7/14
Filed: 1982-12-24
Abstract: PURPOSE:To extend stably the locking range by providing a clock counter and a D/A converter and applying a converter output to a variable frequency oscillator to keep the oscillating frequency of the oscillator to a value equal to the input frequency stably. CONSTITUTION:The clock counter CLC is connected to a phase comparator PC. An output of the CLC is applied to the D/A converter and the output of the converter is applied to a variable frequency oscillator VCO. The CLC generates a signal being a function depending on the output of the PC in the range of change, e.g. in 4 bits. Thus, if the frequency of the VCO is shifted, the output of the PC is changed also and the output of the D/A is changed. Thus, the oscillating frequency of the VCO is shifted to attain synchronism. Although the input to the CLC is lost after the establishment of the synchronism, since the output of the D/A converter keeps the voltage just before the establishment of the synchronism, the oscillating frequency of the VCO is kept stably to a value equal to the input frequency. Thus, the locking range is extended stably.

Abstract: PURPOSE:To detect the optimum position for transferring a semiconductor wafer, prevent the generation of damages in the semiconductor wafer, and thus improve the manufacturing yield by a method wherein a positioning groove provided in a boat for heat treatment is detected by a sensor. CONSTITUTION:A photo receiving element 17 turns on when a pulse signal enters the positioning groove 14 and detects one end part, and turns off when the signal comes out of the groove 14 and detects the other end part. On turning off, the width (a) of the positioning groove 14 is calculated out, in a microcomputer, by the product nXb of pulse feed times between the on and off of the photo receiving element 17 and a time of pulse numbers, which is then divided into two, thus determining the position for transferring the semiconductor wafer. When the photo receiving element 17 turns off, a stage 15 returns to the original position by a control signal from the microcomputer, moves to the transfer position determined by dividing the positioning groove 14 again, and is then stopped. When the stage 15 is stopped at the transfer position, a cassette holder on the stage 15 inclines, and a plurality of semiconductor wafers are transferred to the quartz boat 12 through a comb-form guide part at the same time.
