Abstract
Abstract A production method for producing a semiconductor device by growing a crystalline compound semiconductor on a monocrystalline silicon substrate is comprised of a step for forming a transition domain varying from a monocrystalline silicon layer to a polycrystalline silicon layer in the silicon substrate by implanting oxygen ions into the silicon substrate and annealing the silicon substrate and a step for depositing a compound semiconductor layer on the silicon substrate.
