摘要： A process for the fabrication of an integrated device in a semiconductor chip envisages: forming a semiconductor layer partially suspended above a semiconductor substrate and constrained to the substrate by temporary anchorages; dividing the layer into a plurality of portions laterally separated from one another; and removing the temporary anchorages, in order to free the portions.

摘要： An MOS electronic device is formed to reduce drain/gate capacity and to increase cutoff frequency. The device includes a field insulating layer that covers a drain region, delimits an active area with an opening, houses a body region in the active area, and houses a source region in the body region. A portion of the body region between drain and source regions forms a channel region. A polycrystalline silicon structure extends along the edge of the opening, partially on the field insulating and active layers. The polycrystalline silicon structure includes a gate region extending along a first portion of the edge on the channel region and partially surrounding the source region and a non-operative region extending along a second portion of the edge, electrically insulated and at a distance from the gate region.
