Abstract: A process for manufacturing a silicon carbide semiconductor device includes providing a silicon carbide wafer, having a substrate. An epitaxial growth for formation of an epitaxial layer, having a top surface, is carried out on the substrate. Following upon the step of carrying out an epitaxial growth, the process includes the step of removing a surface portion of the epitaxial layer starting from the top surface so as to remove surface damages present at the top surface as a result of propagation of dislocations from the substrate during the previous epitaxial growth and so as to define a resulting top surface substantially free of defects.

Abstract: SiC-based MOSFET electronic device comprising: a solid body; a gate terminal, extending into the solid body; a conductive path, extending at a first side of the solid body, configured to be electrically couplable to a generator of a biasing voltage; a protection element of a solid-state material, coupled to the gate terminal and to the conductive path, the protection element forming an electronic connection between the gate terminal and the conductive path, and being configured to go from the solid state to a melted or gaseous state, interrupting the electrical connection, in response to a leakage current through the protection element greater than a critical threshold; a buried cavity in the solid body accommodating, at least in part, the protection element.

Abstract: A MEMS sensor has at least a movable element designed to oscillate at an oscillation frequency, and an integrated measuring system coupled to the movable element to provide a measure of the oscillation frequency. The measuring system has a light source to emit a light beam towards the movable element and a light detector to receive the light beam reflected back from the movable element, including a semiconductor photodiode array. In particular, the light detector is an integrated photomultiplier having an array of single photon avalanche diodes.

Abstract: An electronic module for generating light pulses includes an electronic card or interposer, a LASER-diode lighting module, and a LASER-diode driver module. The interposer has an edge recess in which the lighting module is completely inserted. The driver module is arranged on top of the interposer and the lighting module. The electrical connections for driving the LASER diodes are obtained without resorting to wire bonding in order to reduce the parasitic inductances.
