    摘要: Formation of a silicide layer on the source/drain regions of a field effect transistor with a channel under tensile strain is disclosed. The strain is originated by the silicon/carbon source/drain regions which are grown by CVD deposition. In order to form the silicide layer, a silicon cap layer is deposited in situ by CVD. The silicon cap layer is then employed to form a silicide layer made of a silicon/cobalt compound. This method allows the formation of a silicide cobalt layer in silicon/carbon source/drain regions, which was until the present time not possible.

    摘要: The height of epitaxially grown semiconductor regions in extremely scaled semiconductor devices may be adjusted individually for different device regions in that two or more epitaxial growth steps may be carried out, wherein an epitaxial growth mask selectively suppresses the formation of a semiconductor region in a specified device region. In other embodiments, a common epitaxial growth process may be used for two or more different device regions and subsequently a selective oxidation process may be performed on selected device regions so as to precisely reduce the height of the previously epitaxially grown semiconductor regions in the selected areas.

    摘要: An integrated circuit is provided. A gate dielectric is formed on a semiconductor substrate, and a gate is formed over the gate dielectric. A sidewall spacer is formed around the gate and a source/drain junction is formed in the semiconductor substrate using the sidewall spacer. A bottom silicide metal is deposited on the source/drain junction and then a top silicide metal is deposited on the bottom silicide metal. The bottom and top silicide metals are formed into their suicides. A dielectric layer is deposited above the semiconductor substrate and a contact is formed in the dielectric layer to the top silicide.

A gate structure (112) is formed on a major surface (104) of a semiconductor substrate (102). Successive nitride spacers (118, 128) are formed adjacent the sidewalls of the gate structure (112). The nitride spacers (118, 128) are etched and recessed using a single etch to expose the upper portions (115A, 117A) of the gate structure (112). Source (132) and drain (134) regions are formed in the semiconductor substrate (102). Silicide regions (140, 142, 144) are formed on the top surface (109) and the exposed upper portions (115A, 117A) of the gate structure (112) and the source region (132) and the drain region (134). Electrodes (150, 152, 154) are formed in contact with the silicide (140, 142, 144) of the respective gate structure (112), source region (132), and the drain region (134).
