Publication number: 20110284506Abstract: The present invention relates to a heat treatment apparatus that performs activation annealing or defect repair annealing and surface oxidization which succeed impurity doping intended to control the conductive property of a semiconductor substrate. In the present invention, a sample to be heated is placed on a lower electrode in a plasma treatment chamber. A gap between an upper electrode and the lower electrode is filled with a gap whose main raw material is a rare gas (helium, argon, krypton, xenon, or the like) having a pressure close to the atmospheric pressure. A power fed from a high-frequency power supply is applied to the upper electrode in order to induce an atmospheric-pressure glow discharge. Gas heating in the gap between the electrodes, which depends on the glow discharge, is used to heat-treat the sample to be heated.Type: ApplicationFiled: May 12, 2011Publication date: November 24, 2011Inventors: Ken'etsu YOKOGAWA, Masatoshi Miyake
