    Abstract: A method of fabricating a complementary metal oxide semiconductor (CMOS) device, wherein the method comprises forming a first well region (103) in a semiconductor substrate (102) for accommodation of a first type semiconductor device (130); forming a second well region (104) in the semiconductor substrate (102) for accommodation of a second type semiconductor device (140); shielding the first type semiconductor device (130) with a mask (114); depositing a first metal layer (118) over the second type semiconductor device (140); performing a first salicide formation on the second type semiconductor device (140); removing the mask (114); depositing a second metal layer (123) over the first and second type semiconductor devices (130,140); and performing a second salicide formation on the first type semiconductor device (130). The method requires only one pattern level and it eliminates pattern overlay as it also simplifies the processes to form different suicide material over different devices.

    Abstract: A method for providing a dual stress memory technique in a semiconductor device (100) including an nFET (104, 204) and a pFET (106, 206) and a related structure are disclosed. One embodiment of the method includes forming a tensile stress layer (120) over the nFET (104) and a compressive stress layer (122) over the pFET (106), annealing to memorize stress in the semiconductor device and removing the stress layers. The compressive stress layer may include a high stress silicon nitride deposited using a high density plasma (HDP) deposition method. The annealing step may include using a temperature of approximately 400-1200 [err]C. The high stress compressive silicon nitride and/or the anneal temperatures ensure that the compressive stress memorization is retained in the pFET.
