Abstract
PURPOSE: To make uniform the amount of impurity deposition and the diffusion speed, by locating the wafer with an angle to the direction of gas flow.
CONSTITUTION: In the diffusion furnace 10 in which gas G flows, the wafer 14 is held 12 with an angle from the normal line to the gas flow. Each wafer is approximately parallel and the gas smoothly flows between them and no turbulent flow is caused. Thus, the dispersion in the amount of impurity deposition in the wafer and between wafers and in the growing speed of SiO2 can be reduced. The angle tilted is recommended as 45 to 60°
