Latest Patents

Karmous's latest patents include a power semiconductor device and a method of producing such a device. This power semiconductor device features an active region with power cells designed to conduct load current portions between first and second load terminals. Each power cell is constructed with trenches and mesas, which are laterally confined by the trenches and adjoin a drift region. The active mesa within the power cell contains a source region of a first conductivity type and a body region of a second conductivity type, effectively separating the source region from the drift region. Additionally, at least one trench adjacent to the active mesa is configured to induce a conductive channel in the active mesa.

Another significant patent by Karmous is for a voltage-controlled switching device that includes a drain/drift region of a first conductivity type formed in a semiconductor portion. This device features a channel region that is in direct contact with the drain/drift region, as well as a source region of a second conductivity type that is also in direct contact with the channel region. The gate electrode is capacitively coupled to the channel region, allowing for the formation of a first enhancement region of charge carriers in the channel region during the on-state of the device.
