摘要:
An integrated circuit containing an array of SRAM cells with T-shaped contacts in the inverters, in which drain connecting segments may extend beyond gate connecting segments by a distance greater than 10 percent of a separation distance between ends of opposite drain connecting segments. The drain connecting segments may also extend beyond gate connecting segments by a distance greater than one-third of the width of the gate connecting segments. A process of forming an integrated circuit containing an array of SRAM cells with T-shaped contacts in which drain connecting segments may extend beyond gate connecting segments by a distance greater than 10 percent of a separation distance between ends of opposite drain connecting segments. A process may also form the drain connecting segments to extend beyond gate connecting segments by greater than one-third of the width of the gate connecting segments.
