发明名称 Control of local environment for polysilicon conductors in integrated circuits
摘要 A method of fabricating gate level electrodes and interconnects in an integrated circuit, and an integrated circuit so fabricated, with improved process margin for the gate level interconnects of a width near the critical dimension. Off-axis illumination, as used in the photolithography of deep sub-micron critical dimension, is facilitated by the patterned features having a preferred orientation in a common direction, with a pitch constrained to within a relatively narrow range. Interconnects in that same gate level, for example "field poly" interconnects, that run parallel to an array of gate elements are placed within a specified distance range from the ends of the gate elements, or at a distance sufficient to allow sub-resolution assist features.
