Abstract

See full text

A semiconductor device includes first active regions extending in a first direction and having a first number of fins; second active regions extending in the first direction and having a second number of fins, the second number of fins being less than the first number of fins; data transistors formed at least in part in the first active regions; and scan transistors formed at least in part in the second active regions. The data transistors and the scan transistors are included in a scan insertion D flip-flop (SDFQ) that includes a multiplexer serially connected at an internal node to a D flip-flop (FF), the multiplexer including the data transistors for selecting a data input signal, and including the scan transistors for selecting a scan input signal.
