Abstract:
An insulated gate field effect semiconductor component (100) having a source-side halo region (120) and a method for manufacturing the semiconductor component (100). A gate structure (112) is formed on a semiconductor substrate (102). The source-side halo region (120) is formed in the semiconductor substrate (102). After formation of the source-side halo region (120), spacers (127, 128, 152, 154) are formed adjacent opposing sides of the gate structure (112). A source extension region (136A) and a drain extension region (138A) are formed in the semiconductor substrate (102) using an angled implant. The source extension region (136A) extends under the gate structure (112), whereas the drain extension region (138A) may extend under the gate structure (112) or be laterally spaced apart from the gate structure (112). A source region (156) and a drain region (158) are formed in the semiconductor substrate (102).
Abstract:
A semiconductor device comprising a substrate 12 having a first crystal orientation and an insulating layer 40 overlying the substrate 12 is provided. A plurality of silicon layers 16, 30 are formed overlying the insulating layer 40. A first silicon layer 16 comprises silicon having the first crystal orientation and a second silicon layer 30 comprises silicon having a second crystal orientation. In addition, a method of forming a semiconductor device providing a silicon-on-insulator structure comprising a substrate 12 with a silicon layer 16 overlying the substrate 12 and a first insulating layer 14 interposed therebetween is provided. An opening 22 is formed in a first region of the silicon-on-insulator structure by removing a portion of the silicon layer 16 and the first insulating layer 14 to expose a portion 24 of the substrate layer 12. Selective epitaxial silicon 30 is grown in the opening. A second insulating layer 40 is formed in the silicon 30 grown in the opening 22 to provide an insulating layer 40 between the grown silicon 30 in the opening 22 and the substrate 12.
Abstract:
An insulated gate field effect transistor (10) having differentially doped source-side (36A) and drain-side (42A) halo regions and a method for manufacturing the transistor (10). A source-side halo region (36A) is proximal a source extension region (48) and a drain-side halo region (42A) is proximal a drain extension region (52), where the drain-side halo region (42A) has a higher dopant concentration than the source-side halo region (36A). The source extension region (48) extends under a gate structure (22), whereas the drain extension region (52) may extend under the gate structure (22) or be laterally spaced apart from the gate structure (22) or be aligned to the side (26) of the gate structure (22) adjacent the drain region (54). A source region (53) is adjacent the source extension region (48) and a drain region (54) is adjacent the drain extension region (52).
