Abstract
Integrated transistor and method for the production is disclosed. An explanation is given of, inter alia, a transistor having an electrically insulating isolating trench extending from a main area in the direction of a connection region remote from the main area. Moreover, the transistor contains an auxiliary trench extending from the main area as far as the connection region remote from the main area. The transistor requires a small chip area and has outstanding electrical properties.
