Abstract: PURPOSE:To form an impurity region of a specified depth and surface concentration on the surface of a silicon layer by a method wherein thin a film of a specific thickness containing a hydrogen compound with one element out of boron, phosphorus and arsenic is formed in a silicon substrate and then the thin film is annealed. CONSTITUTION:A silicon substrate 20 is held by a holding means 25 and then a reaction gas is fed to a reaction chamber 25 from a feed throat 24a. As for the reaction gas, B2H6 or mixed gas of PH3 with an inert gas is applicable. First, when exciting microwaves (a) are fed from the magnetic field of a plasma producing magnetic field generating means 23 and a microwave leading-in port 21a, several atomic layer-1000Angstrom  thick thin films containing a hydrogen compound with one element out of boron, phosphorus and arsenic are deposited. Secondly, when vacuum-annealed at the temperature not exceeding 900 deg.C, the thin films are diffused to form an impurity region in depth not exceeding 1000Angstrom  and impurity concentration of 10<18>-10<21>cm<-3>. Through these procedures, a shallow junction in excellent controllability can be formed to accelerate the device.
