Abstract
The present disclosure provides a semiconductor structure in accordance with some embodiment. The semiconductor structure includes a semiconductor substrate having a first circuit region and a second circuit region; active regions extended from the semiconductor substrate and surrounded by isolation features; first transistors that include first gate stacks formed on the active regions and disposed in the first circuit region, the first gate stacks having a first gate pitch less than a reference pitch; and second transistors that include second gate stacks formed on the active regions and disposed in the second circuit region, the second gate stacks having a second pitch greater than the reference pitch. The second transistors are high-frequency transistors and the first transistors are logic transistors.
