Original Abstract Submitted
logic circuits are implemented in row cell circuits that include diffusion regions. each diffusion region portion is employed by a transistor in a cell circuit. a current capacity of each transistor depends on a width of the diffusion region portion. a first diffusion region portion and a second diffusion region portion having different widths intersect along an axis, where the diffusion region of a row cell circuit abruptly transitions (e.g., at a square corner) in width. a gate disposed over the diffusion region along the intersection includes a first side on the first diffusion region portion and a second side on the second diffusion region portion. the transition occurring between the first side and the second side of the gate may be achieved by square corner features formed in the diffusion region. such features were not previously achievable at small technology nodes due to mask pattern limitations.
