  • Publication number: 20090186462
    Abstract: A semiconductor device in one embodiment has a first connection region, a second connection region and a semiconductor volume arranged between the first and second connection regions. Provision is made, within the semiconductor volume, in the vicinity of the second connection region, of a field stop zone for spatially delimiting a space charge zone that can be formed in the semiconductor volume, and of an anode region adjoining the first connection region. The dopant concentration profile within the semiconductor volume is configured such that the integral of the ionized dopant charge over the semiconductor volume, proceeding from an interface of the anode region which faces the second connection region, in the direction of the second connection region, reaches a quantity of charge corresponding to the breakdown charge of the semiconductor device only near the interface of the field stop zone which faces the second connection region.

  • Publication number: 20060205122
    Abstract: In a method for fabricating a field stop zone in a semiconductor body of a semiconductor component. According to the method, the semiconductor body is irradiated with protons, and the irradiated semiconductor body is subjected to a heat treatment process. Prior to the irradiation process, the semiconductor body is subjected to an RTA process in a nitriding atmosphere.

  • Publication number: 20060118862
    Abstract: A lateral trench transistor has a semiconductor body having a source region, a source contact, a body region, a drain region, and a gate trench, in which a gate electrode which is isolated from the semiconductor body is embedded. A heavily doped semiconductor region is provided within the body region or adjacent to it, and is electrically connected to the source contact, and whose dopant type corresponds to that of the body region.

  • Publication number: 20050157571
    Abstract: Transistor cells (2) of a power transistor component are in each case provided with a gate conductor structure that forms a gate electrode (52) in sections and is connected via a gate cell terminal (43) to a gate wiring line (81) led to a gate terminal (44) of the power transistor component (1). The gate conductor structure (5) has a desired fusible section (51) with an increased resistance, which is arranged within a cavity. The resistance of the desired fusible section (51) can be set in such a way that, in the event of a current loading of the magnitude of a value that is typical of a defective gate dielectric (41), the gate conductor section (5) is interrupted in the desired fusible section (51) and the gate electrode (52) is disconnected from the gate wiring line (81). The power transistor component can be produced with high yield and has a smaller number of failures during application operation.

  • Publication number: 20030160270
    Abstract: A trench power semiconductor component, in particular an IGBT, has an electrode (4) in a trench (3) that is laterally divided into a section (10) that serves as a gate and a section (11) that is connected to the source metallization (6). A method for making the trench power semiconductor component is also included.

  • Publication number: 20020006703
    Abstract: A field effect transistor configuration with a trench gate electrode and a method for producing the same. An additional highly doped layer is provided in the body region under the source. The layer is used for influencing the conductibility of the source or the threshold voltage in the channel region. Breakdown currents and latch-up effects can thereby be prevented.
