    摘要: Pipe defects in n-type lightly doped drain (NLDD) regions and n-type source/drain (NDS) regions are associated with arsenic implants, while excess diffusion in NLDD and NSD regions is mainly due to phosphorus interstitial movement. Carbon implanatation is commonly used to reduce phosphorus diffusion in the NLDD, but contributes to gated diode leakage (GDL). In high threshold NMOS transistors GDL is commonly a dominant off-state leakage mechanism. This invention provides a method of forming an NMOS transistor in which no carbon is implanted into the NLDD, and the NSD is formed by a pre-amorphizing implant (PAI), a phosphorus implant and a carbon species implant. Use of carbon in the NDS allows a higher concentration of phosphorus, resulting in reduced series resistance and reduced pipe defects. An NMOS transistor with less than 1·1014 cm−2 arsenic in the NSD and a high threshold NMOS transistor formed with the inventive method are also disclosed

    摘要: A process of forming a CMOS integrated circuit including integrating SiGe source/drains in the PMOS transistor after source/drain and LDD implants and anneals. A dual layer hard mask is formed on a polysilicon gate layer. The bottom layer prevents SiGe growth on the polysilicon gate. The top layer protects the bottom layer during source/drain spacer removal. A stress memorization layer may be formed on the integrated circuit prior to a source/drain anneal and removed prior to forming a SiGe blocking layer over the NMOS. SiGe spacers may be formed on the PMOS gate to laterally offset the SiGe recesses.
