Abstract: A method of fabricating an SON structure semiconductor device is described. There is formed, on a silicon substrate, a stack of layers comprising first and second successive combinations. Each successive combination has a bottom silicon-germanium alloy (Site) layer and a top silicon layer. In a conventional way, a gate dielectric layer, a gate, spacers, source and drain regions, and an external passivating layer are formed by ionic implantation. A vertical hole is formed in the gate as far as the bottom Site layer to etch a part of the Site layers to form tunnels. The walls of the hole and the tunnels are then internally passivated so that the tunnels can remain empty or be filled.

Activating light is used having a wavelength greater than the wavelengths of light which the light absorbing compounds absorb. The power of the formed lenses may be controlled by varying the lens forming conditions. Additionally, the lens forming process may be controlled using a microprocessor based control system.
