A method of forming an IC including MOS transistors includes using a gate mask to form a first active gate feature having a line width W1 over an active area and a neighboring dummy feature having a line width 0.8 W1 to 1.3 W1. The neighboring dummy feature has a first side adjacent to the first active gate feature, and a nearest gate level feature on a second side opposite the first side. The neighboring dummy feature defines a gate pitch based on a distance to the first active gate feature or the neighboring dummy feature maintains a gate pitch in a gate array including the first active gate feature. The spacing between the neighboring dummy feature and the nearest gate level feature (i) maintains the gate pitch or (ii) provides a SRAF enabling distance that is ≧2 times the gate pitch and the gate mask includes a SRAF over the SRAF distance.
