The IGBT device is integrated in a chip of semiconductor material including a substrate (205) of a first type of conductivity, an active layer (115,120) of a second type of conductivity formed on an inner surface (210) of the substrate, a body region (125) of the first type of conductivity extending within the active layer from a front surface (130) thereof opposite the inner surface, a source region (135) of the second type of conductivity extending within the body region from the front surface, a channel region (140) being defined within the body region between the source region and the active layer, a gate element (145) insulated from the front surface extending over the channel region, a collector terminal (C) contacting the substrate on a rear surface (255) thereof opposite the inner surface, an emitter terminal (E) contacting the source region and the body region on the front surface, and a gate terminal (G) contacting the gate element. In the solution according to an embodiment of the invention, the IGBT device includes at least one buried emitter region (260) of the first type of conductivity with a concentration of impurities higher than a concentration of impurities of the substrate being formed in a corresponding portion of the substrate, a further portion of the substrate interposed between the at least one buried emitter region and the collector terminal defining an emitter resistor (Re).

Abstract: A self consistent monitoring device comprises a core cell wirelessly RF identifiable and excitable comprising a tag antenna adapted to exchange data with a data acquisition reader device via electromagnetic or magnetic coupling of the tag antenna with an antenna of the reader device, a monolithically integrated circuit including al least a resonance capacitor, a modulator, a rectifier circuit, a charge-pump circuit, a detection circuit, logic and/or analog signal processing circuit, and at least a one tier corolla of identical or different sensor cells around said core cell, covering an area of a monitored structure or body onto which the multi-cellular monitoring device is applied that is a multiple of the individual surface area of a single sensor cell, all sensor cells adapted to convert a change of a geometrical, physical, or chemical parameter or state at the cell location, parameter change and location being detected by the detection circuit of the core cell, upon excitation by said reader device.
Generally, the self consistent monitoring device constitutes a unitary module that is replicated innumerable times over a flexible supporting cloth or plastic film, forming a bi-dimensional tablecloth array of identical or different monitoring devices each covering a certain surface area of a monitored structure or body.
