Abstract

PURPOSE: With the metal layer formed on an insulating layer wherein it is not possible to flow anodiazation current from its rear side, one of the poles of a power supply is connected to the metal layer and a semiconductor substrate in an upright state is gradually immersed by every unit amount into an oxidating solution, whereby anodization is proceeded and uniform oxidized layer is obtained.
