    摘要: A transistor has a JFET gate region of a first conductivity type formed at the face of a semiconductor layer to laterally and downwardly surround a drift region of a second conductivity type. A thick insulator region is formed on a portion of the drift region at the face. A IGFET body of the first conductivity type is formed at the face to be adjacent the JFET gate region. This body spaces a source region of the second conductivity type from the drift region. A drain region is formed at the face to be of the second conductivity type and to adjoin the drift region, and to be spaced from the IGFET body. A conductive gate extends over the face between the source region and the thick insulator region, with a thin gate insulator spacing the gate from the IGFET body. The enhanced doping concentration of the JFET gate region with respect to the semiconductor layer allows the dopant concentration of the drift region to likewise be increased, thereby allowing RESURF conditions to be met at the rated voltage and with a lower r.sub.ds (on).

    摘要: A contact pad including a compliant, electrically conductive polymer is provided in a substrate. The contact pad may include a metallic base, and a metallic upper surface wherein said polymer is intermediate said base and upper surfaces. The pad also may have a recessed upper surface, or have a metallic bump thereon depending upon the specific use intended. The contact pad may be incorporated into a substrate including a base substrate material having an upper surface, an interconnecting layer on the upper surface, a dielectric layer on the interconnecting layer, and at least one compliant, electrically conductive polymeric contact pad extending through the dielectric layer and in contact with the interconnecting layer. The substrate so formed may be a temporary substrate used, for example, in testing of integrated circuit chips. The contact pads are manufactured on a substrate by metallizing the surface of a substrate to form an interconnect layer, coating the interconnect layer with a dielectric layer, patterning the sites of the contact pads on the dielectric layer to selectively expose metallic pad portions of the interconnect layer, and coating the exposed portions of the interconnect layer with a compliant, electrically conductive polymer. Alternatively, the manufacturing may include the steps of metallizing the surface of a substrate to form an interconnect layer, coating a polymer layer on the interconnect layer, defining a metal diffusion mask to establish a pattern for the pad, diffusing conductive metal into the layer as defined by the diffusion mask to provide regions of the polymer layer having metal diffused therein, and stripping the diffusion mask. The polymer may be either conductive or non-conductive when the coating step occurs.

    摘要: In stacked CMOS, a single gate in first level polysilicon is used to address both an n-channel device in the substrate and an overlaid p-channel device. The p-channel polysilicon device has its channel self-aligned to the gate, by the use of a boron-doped oxide at the sidewalls of the gate. This boron-doped oxide provides a dopant source which dopes the second polysilicon layer to provide heavily doped source/drain extension regions which are self-aligned to the gate in first poly. A mask level is still required to pattern the sources and drains, but the self-aligned source/drain extension regions mean that the source/drain mask level can have a reasonable alignment tolerance.
