Abstract
A method of fabricating, from a first semiconductor substrate having two parallel main surfaces, a system including an islet of a semiconductor material surrounded by an insulative material and resting on another insulative material includes forming a layer of a first insulative material, and forming on the top main surface of the first semiconductor substrate a thin semiconductor layer forming the islet of semiconductor material. The thin semiconductor layer can be selectively etched relative to the first semiconductor substrate. A layer of a second insulative material is formed on exposed surfaces of the islet of semiconductor material and the thin semiconductor layer. The method further includes removing the first semiconductor substrate.
