    摘要: A power MOSFET device (40) includes one or more localized regions of doping (61,62,63) formed in a more lightly doped semiconductor layer (42). The one or more localized regions of doping (61,62,63) reduce inherent resistances between the source regions (47,48) and the drain region (41) of the device. The one or more localized regions of doping (61,62,63) are spaced apart from the body regions (44,46) to avoid detrimentally impacting device breakdown voltage. In an alternative embodiment, a groove (122) or trench (152) design is incorporated to reduce JFET resistance (34). In a further embodiment, a gate dielectric layer having a thick portion (77,97,128,158) and thin portions (76,126,156) is incorporated to enhance switching characteristics and/or breakdown voltage.

    摘要: A method for forming a semiconductor device includes forming insulated gate regions (122,222) on a substrate (26) using a first photo-masking step, forming a base region (47) through an opening (143) between the insulated gate regions (122,222), and forming a source region (152) within the base region (47). Next, a protective layer (61) is formed and selectively patterned using a second photo-masking step to form an opening (62) within the first opening (143) and an opening (63) above one of the insulated gate regions (122). Next, a portion (66) of the substrate (26) and a portion (67) of the insulated gate region (122) are removed. Ohmic contacts (74,76) are then formed and patterned using a third photo-masking step. Additionally, a termination structure (81) is described.

    摘要: A high-voltage level translator circuit is disclosed that is suitable for monolithic integration. The level translator circuit comprises serially-connected current sources suitably ratioed so that the gating on of one current source causes a limited voltage rise across the other current source, which is ungated. The circuit is suitable for integration in a junction-isolated monolithic pseudo-complementary CMOS format.

    摘要: A bipolar transistor (10) includes a collector region (13), a base region (14) in the collector region (13), and an emitter region (20) in the base region (14). A portion (18) of an electrical conductor (16) is located over a base width (23) of the bipolar transistor (10). The emitter region (20) is self-aligned to the portion (18) of the electrical conductor (16) and is preferably diffused into the base region (14) in order to decrease the base width (23) without relying on extremely precise alignment between base region (14) and the portion (18) of the electrical conductor (16). The portion (18) of the electrical conductor (16) is used to deplete a portion of the base width (23) of the bipolar transistor (10).
