Abstract
PURPOSE: To reduce the lamination defect by giving the B diffusion from the main surface opposite to the surface where the semiconductor device is formed.
CONSTITUTION: SiO22 is laminated on Si substrate 1, and layer 2 on back surface 1b where no element is formed is removed. And then the B diffusion is given for 10 minutes at about 1000°C to form diffusion layer 3 featuring the surface density of 1020cm-3. Then CVDSiO24 is coated to prevent the rediffusion outside B. With the treatment of about 5 minutes at 1200°C higher than the B diffusion, the lamination defect occurring under the SiO2 layer on surface 1a can be eliminated. Thus, a good semiconductor device can be obtained by forming the element on surface 1a. The ion injection method is also available, and the heat treatment can also be carried out in the inactive gas in the course of the manufacturing processes.
