Abstract: Ein Halbleitergehäuse wird durch Bereitstellen eines Halbleiter-Nacktchips mit einem Anschluss an einer ersten Seite des Nacktchips, einem Bereitstellen eines Materials, das mit dem Nacktchip an einer gegenüberliegenden zweiten Seite des Nacktchips verbunden ist und einem solchen Einbetten des Nacktchips in eine Formmasse hergestellt, so dass der Nacktchip an allen Seiten, mit Ausnahme der ersten Seite, von der Formmasse bedeckt ist. Die Formmasse wird an einer Seite der Formmasse, benachbart zu der zweiten Seite des Nacktchips, gedünnt, um das Material an der zweiten Seite des Nacktchips freizulegen, ohne dabei die zweite Seite des Nacktchips freizulegen. Eine elektrische Verbindung wird mit dem Anschluss an der ersten Seite des Nacktchips ausgebildet. Im Fall eines Transistor-Nacktchips kann der Anschluss ein Source-Anschluss sein, und der Transistor-Nacktchip kann mit der Source nach unten an einem Metallblock wie einem Diepaddle eines Leiterrahmens angebracht sein.

Abstract: The power transistor (1) has a front side (2), a back side (3) and a lateral edge (8). A horizontal barrier plate (6), which has the same potential as the drift zone (9), is attached at the front side between the edge and the edge connector (4). The barrier plate is laminated over a field plate (7), forming a plate capacitor structure. The edge is provided with the same potential as the drift zone. The edge connector is provided to reduce voltage between the edge and the source zone (14). A semiconductor body (27) includes the n-type drift zone, n-type source zones, p-type body zone (13) and the drain zone (10). Gates (15) are formed to complete a metal oxide semiconductor (MOS) structure (12) with the drift zone, source zone and body zone. The edge connector is arranged between the edge and the MOS structure, in which the edge connector is provided with p-type field rings. An independent claim is included for the lateral power transistor.

Abstract: The device has a channel zone (5A,5B,5C) arranged between a connection zone (2) and a drift zone. A first channel (51) formed adjacent to a control electrode is conductive when the control voltage is not equal to zero. A first terminal electrode (22) is connected to the drift zone via at least one second channel (71) of a first conductivity type, conductive when a control voltage is equal to zero. An Independent claim is included for a method of manufacturing a semiconductor device.
