IPC: H01L31/04
Filed: 1987-09-30
Abstract: PURPOSE:To improve open-circuit voltage and short-circuit characteristics of a semiconductor device by forming a P-N junction and pasivation simultaneously in such a manner that material gases are changed in a vapor phase atmosphere to coat one surface of a semiconductor substrate of a first conductivity type with a semiconductor of a second conductivity type and then with an oxide. CONSTITUTION:A P-type silicon substrate 22 is etched at its surface and placed in a low-pressure CVD chamber. An N<+> polysilicon layer 23 is deposited by a low-pressure CVD method using SiH4 or PH3 gas. The N<+> polysilicon layer 23 is coated with silicon dioxide 24 by a low-pressure CVD method using SiH4 or O2 gas. The temperature for the CVD method is low enough to prevent thermal diffusion and thermal oxidation, so that semiconductor characteristics of the substrate will not be degraded. The doped polysilicon 23 provides high open-circuit voltage, while the silicon dioxide film 24 provides good open-circuit and short-circuit characteristics.
