摘要:
A MOSFET device includes one or more active device structures and one or more dummy structures formed from semiconductor drift region and body regions. The dummy structures are electrically connected in parallel to the active device structures. Each dummy structure includes an electrically insulated snubber electrode formed proximate the body region and the drift region, an insulator portion formed over the snubber electrode and a top surface of the body region, and one or more electrical connections between the snubber electrode and portions of the body region and a source electrode. It is emphasized that this abstract is provided to comply with rules requiring an abstract that will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims.
