Title: Heating of semiconductor wafer with light irradiation
Inventor: MIMURA YOSHIKI
IPC: H01L21/268
Filed: 1982-06-30
Abstract: PURPOSE:To prevent the occurrence of a large warppage and a slip line detrimental to the subsequent treatment process by a method wherein the part in the vicinity of the outer periphery of a semiconductor wafer is additionally heated by an auxiliary heating source so as to uniformize the temperature all over the wafer. CONSTITUTION:An auxiliary heating source 2, which is composed of a halogen or infrared bulb and provided with an annular sealed body made of quartz glass as well as a filament 2b within the sealed body, is arranged on the upper or lower side of a wafer 1 at a position distant a little therefrom obliquely outwards for mainly heating a part 1b near the outer periphery of the wafer 1. While the wafer 1 is subjected to main heating on both sides by receiving light irradiation from a planar light source from both above and below, the part 1b in the vicinity of the outer periphery is additionally heated by the auxiliary heating source 2. It is thus made possible to extremely reduce the temperature difference between a center part 1a and the part 1b in the vicinity of the outer periphery, and to uniformize the temperature all over the wafer 1.

Title: Charge detection method and charge detection circuit
Inventor: NOBUE MAMORU
IPC: G01R29/24
Filed: 1990-05-01
Abstract: PURPOSE:To enhance the S/N and to attain high sensitivity by setting a capacitance to a variable capacitor, injecting a charge to the variable capacitor in this state, varying only the capacitance of the variable capacitor while keeping the injected charge and detecting a level caused between both electrodes of the capacitor. CONSTITUTION:The capacitance between metallic electrodes 21 and 24 is a capacitance C1 by a thickness of an insulation layer 22. On the other hand, electrons are made depleted to a semiconductor side at a border between the insulation layer 22 and a semiconductor layer 23 resulting in causing a high resistance by applying a voltage (e.g. -5V) more negative than the voltage of the metallic electrode 24 to the metallic electrode 21. When the layer is sufficiently made depleted, the capacitance between the metallic electrodes 21 and 24 is a capacitance C2 being the combined capacitance of the series connection of the insulation layer 22 and the semiconductor layer 23. Since the capacitance C2 is smaller than the capacitance C1, the capacitance of the variable capacitor CEXT is changed in response to a change in the level of the metallic electrode 21.

Abstract: PURPOSE:To make it possible to detect the change in current flowing through a PTC thermistor by applying a voltage to the PTC thermistor which is self- heated in the temperature region wherein the positive temperature coefficient (PTC) thermistor indicates the PTC charactristic. CONSTITUTION:A PTC thermistor 1 comprises an electrode 1-a and a lead wire 1-b.

Then, e.g., a current flowing through the PTC thermistor 1 is directly measured with an ammeter 2, and the difference in current values is observed. Thus the change in current can be detected.
