Title: Impurity diffusion into semiconductor
Inventor: MONMA NAOHIRO
IPC: H01L21/225
Filed: 1980-03-31
Abstract: PURPOSE:To obtain a uniform diffusion layer with satisfactory reproducibility by diffusing P shallower than a prearranged depth on a silicon substrate, removing an oxidized film after oxidizing at a temperature lower than an eutectic point of P and Si and heating to cause P diffusion at a prearranged depth. CONSTITUTION:If P is diffused on a silicon substrate, it is in the most case, adhered on the surface of the substrate in the form of P2O5, and P2O5 is flocculated on the surface to form a protrusion. Therefore, before ''drive-in'' at a temperature over an eutectic point of P and Si (1,130 deg.C), first P is built up at 800-1,100 deg.C and this sample is washed with an aqueous HF solution. Then it is processed in oxygen at 1,100 deg.C as the first treatment to suppress the growth of an oxidized film to approximately 0.15-0.5mum. Following this procedure, the grown oxidized film is removed with aqueous HF solution and is processed at a temperature over the eutectic point of P and Si as the second thermal treatment. As a result, the growth of protrusionlike specks can be suppressed even at high temperature because of the etching of protrusionlike speck nuclei in a pre-treatment stage. Thus a highly reproducible and uniform diffusion layer is obtained.
