    摘要: Integration schemes are presented which provide for decoupling the placement of deep source/drain (S/D) implants with respect to a selective epitaxial growth (SEG) raised S/D region, as well as decoupling silicide placement relative to a raised S/D feature. These integration schemes may be combined in multiple ways to permit independent control of the placement of these features for optimizing device performance. The methodology utilizes multiple spacers to decrease current crowding effects in devices due to proximity effects between LDD and deep S/D regions in reduced architecture devices.

    摘要: An insulated gate semiconductor device (100) having reduced gate resistance and a method for manufacturing the semiconductor device (100). 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).

    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.
