    摘要: A method of making a lightly doped drain transistor includes the steps of forming a gate electrode (52) and a gate oxide (54) over a semiconductor substrate (56) and forming a drain (70) in a drain region (58) and a source (72) in a source region (60) of the substrate (56). The method further includes generating interstitials (62) near a lateral edge of at least one of the drain (70) and the source (72) and thermally treating the substrate (56). The thermal treatment cause the interstitials (62) to enhance a lateral diffusion (84) of the drain (70) under the gate oxide (54) without substantially impacting a vertical diffusion (82) of the drain (70) or the source (72). The enhanced lateral diffusion (84) results in the formation of at least one of a lightly doped drain extension region (75) and a lightly doped source extension region (76) without an increase in a junction depth of the drain (70) or the source (72). The step of generating interstitials (62) may include the step of implanting at least one of the drain region (58) and the source region (60) of the substrate (56) with a large tilt angle implant which creates the interstitials (62) at a location near the gate oxide (54).

    摘要: A method of forming a silicon-on-insulator semiconductor device including providing a substrate and forming a trench in the substrate, wherein the trench includes opposing side walls extending upwardly from a base of the trench. The method also includes depositing at least two insulating layers into the trench to form a shallow trench isolation structure, wherein an innermost of the insulating layers substantially conforms to the base and the two side walls of the trench and an outermost of the insulating layers spans the side walls of the trench so that a gap is formed between the insulating layers in the trench. The gap creates compressive forces within the shallow trench isolation structure, which in turn creates tensile stress within the surrounding substrate to enhance mobility of the device.

    摘要: A method of reducing an effective channel length of a lightly doped drain transistor (50), includes the steps of forming a gate electrode (52) and a gate oxide (54) over a semiconductor substrate (56) and implanting a drain region (58) of the substrate (56) with a sub-amorphous large tilt angle implant to thereby supply interstitials (62) at a location under the gate oxide (54). The method also includes forming a lightly doped drain extension region (66) in the drain region (58) of the substrate (56) and forming a drain (70) in the drain region (58) and forming a source extension region (67) and a source (72) in a source region (60) of the substrate (56). Lastly, the method includes thermally treating the substrate (56), wherein the interstitials (62) enhance a lateral diffusion (84) under the gate oxide (54) without substantially impacting a vertical diffusion (86) of the extension regions (66, 67), thereby reducing the effective channel length without an increase in a junction depth of the drain (70) and the drain extension region (66) or the source (72) and the source extension region (67).

    摘要: The halo implant technique described herein employs a halo implant mask that creates a halo implant shadowing effect during halo dopant bombardment. A first transistor device structure and a second transistor device structure are formed on a wafer such that they are orthogonally oriented to each other. A common halo implant mask is created with features that prevent halo implantation of the diffusion region of the second transistor device structure during halo implantation of the diffusion region of the first transistor device structure, and with features that prevent halo implantation of the diffusion region of the first transistor device structure during halo implantation of the diffusion region of the second transistor device structure. The orthogonal orientation of the transistor device structures and the pattern of the halo implant mask obviates the need to create multiple implant masks to achieve different threshold voltages for the transistor device structures.
