Title: Substrate temperature calibrating method
Inventor: SASAKI NARIHITO
IPC: G01K7/00
Filed: 1989-10-17
Abstract: PURPOSE:To enable accurate temperature calibration and to reduce the degree of contamination of a grown film by calibrating the temperature of a substrate which is measured by a thermocouple by utilizing an electron diffraction image obtained by irradiating a dielectric with an electron beam. CONSTITUTION:The dielectric 2 for substrate temperature calibration and the substrate 1 are placed on a supporting base 3. Then the temperature of the substrate is raised gradually while looking at the temperature displayed on a temperature controller according to an electromotive force detected by the thermocouple 6. The dielectric 2, on the other hand, is irradiated by an electron gun 4. While the temperature is low, the resistivity of the dielectric 2 is high, and consequently charge accumulating effect is caused, so that no electron beam diffraction image is obtained from the dielectric 2. When the temperature is further raised, the resistivity of the dielectric 2 is decreased and the electron beam diffraction image from the dielectric 2 is obtained on a fluorescent plate 5. The difference from the temperature measured by the thermocouple when the electron beam diffraction image is obtained is calculated and added to the actually set temperature of the substrate to perform the calibration. Further, the dielectric 2 is used, so the substrate is never contaminated.

Abstract: PURPOSE:To improve throughput by omitting a look-in processing for reading- out a processing request to the central processing unit of a line system controller from a processing request memory area concerning the line system controller of a standby system. CONSTITUTION:In parts corresponding to line system controllers 3-1-3-n of a current system, information required for execution are stored completely and in parts corresponding to line system controllers 4-1-4-n of the standby system, information showing unnecessity for the execution of the look-in processing are stored completely. Therefore, only concerning the line system controllers 3-1-3-n of the current system, a request detection part 5 reads out the relevant area of a processing request memory area 7. When the processing request is stored, it is sent out to a request processing part 6 of a central processing unit 1 and the contents of the request are processed in the request processing part 6. Thus, the request detection part 5 executes the look-in processing to the processing request memory area 7 only concerning the line system controllers 3-1-3-n of the current system and the look-in processing is omitted to the line system controllers 4-1-4-n of the standby system.
