    摘要: A semiconductor process and apparatus uses a predetermined sequence of patterning and etching steps to etch an intrinsic polysilicon layer (26) formed over a substrate (11), thereby forming etched gates (62, 64) having vertical sidewall profiles (61, 63). While a blanket nitrogen implant (46) of the intrinsic polysilicon layer (26) may occur prior to gate etch, more idealized vertical gate sidewall profiles (61, 63) are obtained by fully doping the gates (80, 100) during the source/drain implantation steps (71, 77, 91, 97) and after the gate etch.

    摘要: A metal layer is formed over a metal oxide, where the metal oxide is formed over a semiconductor substrate. A predetermined critical dimension of the metal layer is determined. A first etch is performed to etch the metal layer down to the metal oxide and form footings at the sidewalls of the metal layer. A second etch to remove the footings to target a predetermined critical dimension, wherein the second etch is selective to the metal oxide. In one embodiment, a conductive layer is formed over the metal layer. The bulk of the conductive layer may be etched leaving a portion in contact with the metal layer. Next, the portion left in contact with the metal layer may be etched using chemistry selective to the metal layer.

    摘要: Forming structures such as fins in a semiconductor layer according to a pattern formed by oxidizing a sidewall of a layer of oxidizable material. In one embodiment, source/drain pattern structures and a fin pattern structures are patterned in the oxidizable layer. The fin pattern structure is then masked from an oxidation process that grows oxide on the sidewalls of the channel pattern structure and the top surface of the source/drain pattern structures. The remaining oxidizable material of the channel pattern structure is subsequently removed leaving a hole between two portions of the oxide layer. These two portions are used in one embodiment as a mask for patterning the semiconductor layer to form two fins. This patterning also leaves the source/drain structures connected to the fins.
