Latest Patents

One of Alessandria's latest patents is for a diode with insulated anode regions. This diode is integrated on a semiconductor chip with anode and cathode surfaces positioned opposite each other. It features a cathode region that extends inwardly from the cathode surface, a drift region between the anode surface and the cathode region, and multiple anode regions extending from the anode surface within the drift region. The design includes a cathode electrode connected to the cathode region and an anode electrode that contacts certain anode regions while remaining insulated from floating anode regions. This configuration allows charge carriers to be injected from the floating anode regions into the drift region when a control voltage surpasses a threshold voltage.

Another notable patent involves an integrated power device on a semiconductor substrate with an improved trench gate structure. This power device incorporates several conductive bridges within a trench gate structure. The semiconductor substrate features a trench with sidewalls and a bottom, which are covered with a first insulating coating layer that also includes a conductive gate structure. The design allows for the formation of a conductive gate structure that covers the sidewalls with a second conductive coating layer made of a different conductive material, resulting in a central region that forms multiple conductive bridges.
