Abstract
Disclosed is a method of fabricating semi-conductor devices comprising the steps of: forming non-singlecrystalline semiconductor layer on a singlecrystalline insulation substrate, ion-implanting selectively material, which reacts with the semi-conductor layer to form insulating material, into the semiconductor layer; and applying an energy radiation or a heat treatment to the semiconductor layer, whereby the non-singlecrystalline semiconductor layer portion not implanted with said material is singlecrystallized with a seed of the singlecrystalline insulation substrate and at the same time the non-singlecrystalline semiconductor layer portion implanted with the material is rendered insulated.
