    Abstract: PROBLEM TO BE SOLVED: To provide a power device which does not raise problems related to threshold voltage, even if a normal insulating material is used for forming an insulating spacer and will not raise strain causing dislocations or cracks in silicon, even if another material such as silicon nitride is used. SOLUTION: This power semiconductor device has a second insulating material region 10 positioned at a side part of a polysilicon layer 5 and a first insulating material region 6, and at the upper side of a region 14 positioned near the opening at the upper side of an insulation layer body region 2 of a gate oxide layer 4, an oxide region 9 formed between a polysilicon region 5 and the second insulating material region 10, and an oxide spacer 8 formed in the upper side of a second material region.

    Abstract: PROBLEM TO BE SOLVED: To improve electric connection between an electronic power device and a package and avoid the formation of an uncontrollable chemical composition area. SOLUTION: The electronic power device (1) having an improved structure is manufactured by employing MOS technique so as to have at least one gate finger area (3) and related source areas (4) positioned at both sides of the area (3). The electronic power device is provided with at least first level metallic layers (3', 4') arranged so as to be contacted individually with the gate finger area and the source areas, and a passivation layer (5) for protection which is arranged so as to cover the gate finger area. A wetting metallic layer (7) is advantageous to be built up on the passivation layer and the first level metallic layer (4') for covering the source area. According to this method, an additional wetting metallic layer functions as a second level metallic layer.

    Abstract: PROBLEM TO BE SOLVED: To provide the structure of a high density MOS technology power device provided with a first conductivity-type base area formed in a second conductivity-type semiconductor layer. SOLUTION: A base area has at least pairs of substantially linear and substantially parallel base stripes 32. The respective base stripes 32 are connected to the adjacent base stripes 32 at end parts by a junction area. Thus, at least the pairs of base stripes 32 and the junction area can form continuous meandered base areas 31A-31D.

    Abstract: A manufacturing process for obtaining integrated structure bipolar transistors with controlled storage time comprises the steps of: in a silicon material (1, 2), forming at least one bipolar transistor occupying a first area (AD) on a first surface of the silicon material (1, 2); covering the first surface of the silicon material (1, 2) with an insulating material layer (5); selectively removing the insulating material layer (5) to open at least one window (6) having a second area (APt) much smaller than the first area (AD) occupied by the bipolar transistor; implanting into the silicon material (1, 2) a medium dose (D) of platinum ions through said window (6); and diffusing into the silicon material (1, 2) the implanted platinum ions to obtain a uniform distribution of platinum inside the transistor.
