    Abstract: At edge termination region (12), a trench (22) is disposed near an interface of an active region (11). Inside the trench (22), an embedded insulating film (23) is embedded, and inside the embedded insulating film (23), a FP (45) long in a direction of depth is disposed. The FP (45) curves outwardly away from an inner side wall (22a) of the trench (22) as a depth from a base front surface increases. At least near a bottom end of the FP (45), a distance (w3) between the FP (45) and the inner side wall (22a) of trench (22) is greater than a width (w2) of the groove (24). The FP (45) is connected to a front surface electrode (4) that extends on the embedded insulating film (23). As a result, breakdown voltage can be enhanced, adverse effects of the surface charge can be reduced, and chip size can be further reduced.

    Abstract: An ESD protection circuit (100) and device structure (200) comprises five transistors (101, 102, 103, 104 and 105), two PNP and three NPN. The five transistors are coupled together so that a first NPN and PNP pair (101, 102) constitute a first silicon controlled rectifier, SCR. The NPN transistor 102 of the first SCR and a third transistor (103) of NPN type are coupled so that they constitute a Darlington pair. A further NPN and PNP pair (104, 105) are coupled together to form a second SCR with the collector of the PNP transistor of the first SCR being coupled with the emitter of the PNP transistor (104) of the second SCR. The circuit is particularly suitable for high voltage triggering applications and two or more devices may be cascaded in series in order to further increase the triggering voltage.

    Abstract:  ダブルリサーフ構造からなる高耐圧分離構造を有する半導体装置であって、低電位領域と高電位領域とを分離する高耐圧分離構造を備える。高耐圧分離構造は、平面形状が環状の帯状で、直線部分と、当該直線部分に繋がるコーナー部分とからなる。高耐圧分離構造において、n型のウェル領域の基板おもて側の表面層には、n型のウェル領域の外周に沿ってp型のリサーフ領域が形成されている。リサーフ領域の単位面積当たりの総不純物量を直線部分に比べてコーナー部分で少なくすることで、コーナー部分での耐圧曲線(32)のピーク値となるドーズ量の位置(32a)を直線部分での耐圧曲線(31)のピーク値となるドーズ量の位置(31a)に合わせることができる。その結果、素子耐圧を高くすることができて、プロセスのばらつきによる素子耐圧の低下を抑制することができる。

    Abstract: Integrated active area isolation structure for transistor to replace larger and more expensive Shallow Trench Isolation or field oxide to isolate transistors. Multiple well implant is formed with PN junctions between wells and with surface contacts to substrate and wells so bias voltages applied to reverse bias PN junctions to isolate active areas. Insulating layer is formed on top surface of substrate and interconnect channels are etched in insulating layer which do not go down to the semiconductor substrate. Contact openings for surface contacts to wells and substrate are etched in insulating layer down to semiconductor layer. Doped silicon or metal is formed in contact openings for surface contacts and to form interconnects in channels. Silicide may be formed on top of polycrystalline silicon contacts and interconnect lines to lower resistivity. Any JFET or MOS transistor may be integrated into the resulting junction isolated active area.
