A silicon-based light-emitting device is described and comprises an active region, an excitation system which can bring about a condition of inversion of the population of carriers within the active region, and semi-reflective elements which can define a resonant optical structure in which the active region is inserted so as to bring about stimulated emission of coherent light. The active region comprises silicon nanostructures immersed in a silicon-dioxide-based dielectric matrix.

Laser device based on silicon nanostructures

An electronic power device is integrated on a substrate of semiconductor material having a first conductivity type, on which an epitaxial layer of the same type of conductivity is grown. The power device comprises a power stage PT and a control stage CT, this latter enclosed in an isolated region having a second type of conductivity type. The power stage PT comprises a first buried area having the second type of conductivity type and a second buried area, partially overlapping the first buried area and having the first conductivity type. The isolation region and the control stage CT comprise respectively a third buried area, having the second conductivity type, and a fourth buried area, partially overlapped to the third buried area and having the first conductivity type. Said first, second, third and fourth buried areas are formed in the epitaxial layers at a depth sufficient to allow the power stage PT and the control stage CT to be entirely formed in the epitaxial layers.
