Abstract: A method and device for improving the channel doping profile of deep-submicron field effect transistors and MOSFETs. The method involves forming a multi-graded lateral channel doping profile by dual halo implants annealed at different temperatures to improve the threshold voltage roll-off characteristics of MOSFETs of 50 nm or less. The method includes forming a spacer on the sidewalls of a gate, followed by forming source/drain regions by epitaxial growth followed by a deep source/drain implant and anneal. After removal of the spacer, the first angled deep halo implant through the space formed by removal of the spacer and a second annealing at a temperature lower than the first anneal occurs. A second angled halo implant and a third anneal at a temperature less than the second anneal is performed. The microelectronic chip is then silicided and the MOSFET is further completed.

Abstract: A MOSFET transistor and method of fabrication are described for engineering the channel dopant profile within a MOSFET transistor utilizing a single deep implantation step and solid-phase epitaxy. The method utilizes the formation of an L-shaped spacer having reduced height “cutouts” adjacent to the gate stack. The L-shaped spacer is preferably created by depositing two layers of insulating material, over which a third spacer is formed as a mask for removing unwanted portions of the first and second insulation layers. Amorphization and deep implantation is performed through the L-shaped spacer, wherein the junction contour is profiled in response to the geometry of the L-shaped spacer, such that a single deep implantation step may be utilized. Pocketed steps within the contoured junction reduce short-channel effects while allowing the formation of silicide to a depth which exceeds the junction depth implanted beneath the gate electrode.

Abstract: A method for making a ULSI MOSFET chip includes forming transistor gates on a substrate and a semiconductor device thereby made. The gates are formed by depositing a polysilicon layer on the substrate, implanting germanium into the polysilicon layer at a comparatively low dose, and then oxidizing the doped polysilicon layer. Under the influence of the oxidation, the germanium is repelled from an upper sacrificial region of the polysilicon layer into a lower gate region of the polysilicon layer, thereby increasing the germanium concentration in the lower gate region. The sacrificial region is then etched away and an undoped polysilicon film deposited on the gate region. Subsequently, the gate region with undoped polysilicon film is patterned to establish a MOSFET gate, with the substrate then being appropriately processed to establish MOSFET source/drain regions.
