    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 process for forming a metal silicide gate in an FET device, where the suicide is self-forming (that is, formed without the need for a separate metal/silicon reaction step), and no CMP or etchback of the silicon material is required. A first layer of silicon material (3) (polysilicon or amorphous silicon) is formed overlying the gate dielectric (2); a layer of metal (4) is then formed on the first layer (3), and a second layer of silicon (5) on the metal layer (4). A high-temperature (greater than 700 0C) processing step, such as source/drain activation anneal, is subsequently performed; this step is effective to form a silicide layer (30) above the gate dielectric (2) by reaction of the metal with silicon in the first layer. A second high-temperature processing step (such as source/drain silicidation) may be performed which is effective to form a second silicide layer (50) from silicon in the second layer (5). The thicknesses of the layers are such that in the high-temperature processing, substantially all the first layer and at least a portion of the second layer are replaced by silicide material. Accordingly, a fully suicided gate structure may be produced.

    Abstract: The present invention relates to a semiconductor device comprising at least one n-channel field effect transistor (n-FET). Specifically, the n-FET comprises first and second patterned stressor layers that both contain a carbon-substituted and tensilely stressed single crystal semiconductor. The first patterned stressor layer has a first carbon concentration and is located in source and drain (S/D) extension regions of the n-FET at a first depth. The second patterned stressor layer has a second, higher carbon concentration and is located in S/D regions of the n-FET at a second, deeper depth. Such an n-FET with the first and second patterned stressor layers of different carbon concentration and different depths provide improved stress profile for enhancing electron mobility in the channel region of the n-FET.

    Abstract: PROBLEM TO BE SOLVED: To provide a multilayer embedded stressor which is used in a semiconductor structure causing deformation in a device channel area and has a gradual dopant distribution structure. SOLUTION: This multilayer stressor is formed in a portion of a semiconductor structure where a source/drain area is generally positioned. This multilayer stressor comprises a first co-epitaxial semiconductor layer not doped or doped at a low concentration and a second epitaxial semiconductor layer doped at higher concentration than the first epitaxial semiconductor layer. Each of the first and second epitaxial layers has an identical lattice constant. The lattice constant differs from that of a substrate where each semiconductor layer is embedded. A structure including this multilayer embedded stressor ensures a good balance between an adjacent stress and a short channel effect and eliminates or substantially reduces any defects which generally occur during deeper source/drain area formation.
