    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 vertical IGFET configuration includes a stripe arrangement having a non-linear shape. In one example, a stripe arrangement (30) has contact cut-out portions (41) and elongated portions (42). The elongated portions (42) have a width (44) that less than the width (43) of the contact cut-out portions (41). The stripe arrangement (30) increases channel density compared to typical individual cell configurations (10) and straight stripe configurations (20) thereby lowering on-resistance.

    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.
