Transistor Component

摘要

A transistor component includes a semiconductor body, a first main electrode, a gate contact electrode, a plurality of transistor cells, and a plurality of gate electrodes. The semiconductor body has a drain region and a drift region of a first conduction type, and a body region of a second conduction type. The first main electrode is on a top side of the semiconductor body. The plurality of gate electrodes is electrically connected to the gate contact electrode and arranged successively in a first lateral direction. In the plurality, a first gate electrode is next to a second gate electrode. The first main electrode includes a first trench contact finger, between the first gate electrode and the second gate electrode, and a second trench contact finger, between the first gate electrode and the second gate electrode, electrically connecting the first main electrode to the body region.
