    摘要: First example embodiments comprise forming a stress layer over a MOS transistor (such as a LDMOS Tx) comprised of a channel and first, second and third junction regions. The stress layer creates a stress in the channel and the second junction region of the Tx. Second example embodiments comprise forming a MOS FET and at least a dummy gate over a substrate. The MOS is comprised of a gate, channel, source, drain and offset drain. At least one dummy gate is over the offset drain. A stress layer is formed over the MOS and the dummy gate. The stress layer and the dummy gate improve the stress in the channel and offset drain region

    摘要: A structure and a process for a self-aligned vertical PNP transistor for high performance SiGe CBiCMOS process. Embodiments include SiGe CBiCMOS with high-performance SiGe NPN transistors and PNP transistors. As the PNP transistors and NPN transistors contained different types of impurity profile, they need separate lithography and doping step for each transistor. The process is easy to integrate with existing CMOS process to save manufacturing time and cost. As plug-in module, fully integration with SiGe BiCMOS processes. High doping Polysilicon Emitter can increase hole injection efficiency from emitter to base, reduce emitter resistor, and form very shallow EB junction. Self-aligned N+ base implant can reduce base resistor and parasitical EB capacitor. Very low collector resistor benefits from BP layer. PNP transistor can be Isolated from other CMOS and NPN devices by BNwell, Nwell and BN+ junction.
