Title: Manufacture of semiconductor integrated circuit provided with embedded diffusion layer
Inventor: TSUNODA YOSHIHIRO
IPC: H01L21/324
Filed: 1989-01-21
Abstract: PURPOSE:To prevent a lattice defect from being caused, to easily control a layer resistance and to form a diffusion face whose surface state is good by a method wherein, in an amorphous silicon layer on an embedded diffusion region of a silicon single-crystal substrate, the amorphous silicon layer into which arsenic ions have been implanted at a solid epitaxial growth temperature is oxidized completely near its surface and, in addition, arsenic is diffused into the embedded diffusion region. CONSTITUTION:A silicon dioxide film 2 for arsenic diffusion mask use is formed on a P-type silicon single-crystal substrate 1; after that, the silicon dioxide film 2 on a region in which an embedded diffusion layer region is to be formed is removed. Then, an amorphous silicon film 3 is deposited. Arsenic ions 4 are implanted into the whole surface of the amorphous silicon layer 3. Then, while the amorphous silicon layer 3 on the silicon single-crystal substrate 1 is being grown by a solid epitaxial growth operation, it is oxidized; it is steam-oxidized at 1000 deg.C in a wet oxygen atmosphere; the amorphous silicon film 3 is oxidized completely. Then, arsenic ions are diffused by using the completely oxidized amorphous silicon layer 3 as a diffusion source; a layer resistance is lowered. Thereby, it is possible to form an embedded diffusion region 7 in which the surface of a diffusion layer is smooth and free of detects.
