Title: Method and apparatus of high-temperature high-pressure treatment for semiconductor wafer
Inventor: FUJIKAWA TAKAO
IPC: H01L21/00
Filed: 1999-03-26
Abstract: PROBLEM TO BE SOLVED: To inhibit a heater from generating particles by installing the heater in a treatment chamber, where wafers are to be stacked up, so that treatment is performed while heating power is supplied to the heater with direct current. SOLUTION: A heater 13 is installed in a treatment chamber S, in which a heat insulation structure 10 is incorporated, under a wafer 15, which is placed above a bottom cover 8, and employs an electrical resistance wire heating system. One to twenty-five semiconductor wafers are placed on a portable wafer support, which supports wafers at three or four points along the circumference of a wafer. An electric furnace, which comprises the heat insulation structure 10 and heater 13, supplies heating energy by feeding direct current through the heater 13. Feeding direct current instead of alternating current can prevents occurrence of oscillations. Thus, no particles are generated even if both the heater 13 and semiconductor wafer 15 are placed in the treatment chamber S incorporating the heat insulation structure 10, preventing contamination caused by particles.
