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: PROBLEM TO BE SOLVED: To realize an interconnection structure that improves the adhesion between an upper low-k dielectric layer and a diffusion barrier cap dielectric layer existing therebeneath. SOLUTION: In the interconnection structure, adhesion between the upper low-k (for example, the dielectric coefficient is less than 4.0) dielectric layer (for example, a dielectric containing an element group consisting of Si, C, O, and H) and the diffusion barrier cap dielectric layer (for example, a cap layer containing an element group consisting of C, Si, N, and H) existing therebeneath is improved, by providing an adhesion transition layer in between the two layers. Because the adhesion transition layer exists between the upper low-k dielectric layer and the diffusion barrier cap dielectric layer, the possibility that the layers in the interconnection structure are separated in a packaging process is reduced. The adhesion transition layer provided here comprises a lower SiO x (or SiON) contained region and an upper C inclination region. Such a structure and, in particular, a method for forming an adhesion transition layer are also provided. COPYRIGHT: (C)2006,JPO&NCIPI
