Abstract

In a method for the fabrication of a layer of a monocrystalline semiconducting layer on a layer of insulating material, an epitaxial growth is achieved in a cavity closed by layers of dielectric material, using a seed of monocrystalline semiconducting material of a substrate. The growth takes place first of all, vertically, perpendicularly to the seed, and then horizontally in the plane of the cavity. This method thus enables a three-dimensional integration of semiconductor components.
