  • Patent number: 8703608
    Abstract: 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.

  • Publication number: 20120091531
    Abstract: An integrated circuit constructed according to an arrangement of logic blocks, with one or more logic blocks including transistors of a different threshold voltage than in other logic blocks. Spacing between neighboring active regions of different threshold voltages is minimized by constraining the angle of implant for the threshold adjust implant, and by constraining the thickness of the mask layer used with that implant. These constraints ensure adequate implant of dopant into the channel region while blocking the implant into channel regions not subject to the threshold adjust, while avoiding shadowing from the mask layer. Efficiency is attained by constraining the direction of implant to substantially perpendicular to the run of the gate electrodes in the implanted regions.
