Title: Oxidizing furnace for semiconductor substrate
Inventor: KASHIHARA TOMIO
IPC: C23C8/06
Filed: 1979-12-10
Abstract: PURPOSE:To control a heater input and control a temperature by a method wherein proportional integral differential (PID) operation is performed by means of a signal for correcting the temperature difference between a substrate in conjunction with a lot proceeding and a thermoelectric couple attached to a heater. CONSTITUTION:Along with an accumulation of SiO2, the drop of the temperature of a substrate proceeds as DELTAT11, DELTAT12.... This quantity is implemented again after an oxidizing furnace is flushed once more. Accordingly, a quantity equivalent to DELTATIN is previously set as a resistance ratio R0/(R0+R1), R0/(R0+R2)... and this is added to the set value of each stage and then added to an input signal of each PID to control the temperature of each of heaters 14a-14c. Resistors R1, R2... are changed over every time a lot proceeds by means of a rotary relay. With this control system, the actual temperature variation of an Si substrate which was impossible in the past, can be corrected and the temperature variation during a reaction and the temperature variation among lots can be retained within the range of + or -0.5 deg.C, thus, improving the yield of IC sharply.

IPC: G11B5/027
Filed: 1978-12-20
Abstract: PURPOSE: To increase the reproduction output of the low band by installing the 2nd magnetic head featuring more than double gap compared with the 1st magnetic head on the same track with the fixed space secured between these two magnetic heads and then adding the reproduction output of the 1st magnetic head with delay of a fixed time.  
     CONSTITUTION: The same recording locus is reproduced via 1st and 2nd magnetic head 8 and 10. The reproduction signal of head 8 is added to the reproduction signal of head 10 after delayed by time tO via delay element 9. This time tO is set for the period during which the same point of the tape reaches the center of gap 12 of head 10 from the center of gap 11. As a result, the higher output can be obtained over the entire frequency range than the reproduction via one unit of the head. And if the gap length of head 8 is set more than double the gap length of head 10, the dynamic range can be increased for the low band. Thus the reproduction output can be increased at the low frequency band with no fluctuation of the level nor increment of distortion.
