  • Patent number: 8841186
    Abstract: The disclosed method of manufacturing (110, 120, 130, 140) a semiconductor device (12) has the steps (112, 114, 116) of: forming at least one wall (33) of a body (44) of the semiconductor device (12) by etching at least one trench (22) for a gate (42) of the semiconductor device (12) into the body (44); and performing a slanted implantation doping (126, 128) into the at least one wall (33) of the body (44), after the etching (112) of the at least one trench (22) and prior to coating the at least one trench (22) with an insulating layer (29).
    Type: Grant
    Filed: March 4, 2010
    Date of Patent: September 23, 2014
    Assignee: X-Fab Semiconductor Foundries AG
    Inventors: Alexander Hoelke, Deb Kumar Pal, Kia Yaw Kee, Yang Hao
  • Patent number: 8759942
    Abstract: The present invention provides semiconductor devices and methods for fabricating the same, in which superior dielectric termination of drift regions is accomplished by a plurality of intersecting trenches with intermediate semiconductor islands. Thus, a deep trench arrangement can be achieved without being restricted by the overall width of the isolation structure.

  • Patent number: 7491925
    Abstract: The aim of the invention is to configure a photodetector (10) such that no disadvantages are created for processing low luminous intensities on detectors known in prior art, especially when monolithically integrating the evaluation electronics. Said aim is achieved by a photodetector for processing low luminous intensities, comprising a monolithically integrated transimpedance amplifier and monolithically integrated evaluation electronics. An actual photocell component (20) is assigned to the chip face onto which the light preferably falls. Electronic circuit components (30) are arranged on the opposite chip face. Electrical connections (40) between the photocell and the electronic circuit are provided with an extension in the direction running perpendicular to the chip normal.
