Filed: 1990-05-07
Abstract: PURPOSE:To prevent the generation of boron particles of a large crystalline form by a method wherein a semiconductor substrate is left to stand in a nitrogen atmosphere for prescribed hours or longer after a doping process. CONSTITUTION:A silicon wafer 1 is erected on a groove in a quartz boat, is heated at about 750 deg.C in carrier gas, such as N2 gas or the like, along with a PBN plate to perform a doping process and a high-concentration boron glass layer 4 is adhered on the surface of the wafer. The wafer is stored in an atmosphere, in which N2 gas is made to flow at a flow rate of 10l/minute, for 1.5 hours or longer along with the boat. The wafer is detached from the boat under a clean booth of 30% of lower of a humidity and is erected on a groove in another boat. This boat is moved to a diffusion furnace, in which such carrier gas an N2 gas or the like is made to flow, and a drive process at 1000 deg.C or higher is performed to form a p-type region 5 of a prescribed depth. It may be though that in case boron glass comes into contact to a moisture containing atmosphere and there is a boron crystal in the vicinity of the boron glass, the boron glass is adhered on the crystal to recrystallize and large crystal grains are generated. Accordingly, when the wafer is left to stand in the nitrogen atmosphere for 1.5 hours after the doping process, a large crystallization of the wafer due to the reaction of the wafer to water is prevented from being generated.
