    摘要: Semiconductor doping techniques, along with related methods and structures, are disclosed that produce components having a more tightly controlled source and drain extension region dopant profiles without significantly inducing gate edge diode leakage. The technique follows the discovery that carbon, which may be used as a diffusion suppressant for dopants such as boron, may produce a gate edge diode leakage if present in significant quantities in the source and drain extension regions. As an alternative to placing carbon in the source and drain extension regions, carbon may be placed in the source and drain regions, and the thermal anneal used to activate the dopant may be relied upon to diffuse a small concentration of the carbon into the source and drain extension regions, thereby suppressing dopant diffusion in these regions without significantly inducing gate edge diode leakage. The increased concentration of carbon in the source and drain regions may permit heavier doping of the source/drain region, leading to improved gate capacitance.

    摘要: A method for manufacturing a semiconductor device featuring a high-stress dielectric layer is disclosed. The method involves the deposition of a comparatively thick liner layer that exerts increased strain on an underlying gate and active areas, resulting in enhanced carrier mobility through the transistor and heightened transistor performance. The method also involves the amelioration of fabrication problems that might arise from the deposition of a comparatively thick liner layer by forming such layer with at least a partially direction deposition process. Also disclosed are semiconductor devices manufactured in accordance with the disclosed methods.

    摘要: A method (200) of forming an isolation structure is presented, in which a hard mask layer (304, 308) is formed (204, 206) over the isolation and active regions (305, 303) of a semiconductor body (306), and a dopant is selectively provided to a portion of the active region (303) proximate the isolation region (305) to create a threshold voltage compensation region (318). After the compensation region (318) is created, the hard mask layer (304, 308) is patterned (218) to create a patterned hard mask. The patterned hard mask is then used in forming (222) a trench (323) in the isolation region (305) near the compensation region (318), and the trench (323) is then filled (224) with a dielectric material (338).

    摘要: The present invention pertains to forming respective silicides on multiple transistors in a single process. High performance is facilitated with simple and highly integrated process flows. As such, transistors, and an integrated circuit containing the transistors, can be fabricated efficiently and at a low cost. The different silicides can be formed with different materials and/or to different thicknesses. As such, the silicides can have different electrical characteristics, such as resistivity and conductivity. These different attributes instill the transistors with different work functions when formed as gate contacts thereon. This provides an integrated circuit containing the transistors with diverse operating capabilities allowing for the execution of operations requiring more flexibility and/or functionality.
