Patents by Inventor MARIO KLEINDIENST

MARIO KLEINDIENST has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Semiconductor device and trench field plate field effect transistor with a field dielectric including thermally grown and deposited portions
    Patent number: 9905685
    Abstract: A semiconductor device includes compensation structures that extend from a first surface into a semiconductor portion. Sections of the semiconductor portion between neighboring ones of the compensation structures form semiconductor mesas. A field dielectric separating a field electrode in the compensation structures from the semiconductor portion includes a thermally grown portion, which directly adjoins the semiconductor portion. A not fully densified deposited portion of the field dielectric has a lower density than the thermally grown portion.
    Type: Grant
