Abstract

In a semiconductor device having MONOS memories configured by fin-type MISFETs, an increase in parasitic capacitance between wirings accompanying miniaturization of the semiconductor device is prevented, and the reliability of the semiconductor device is improved. In a memory cell array in which a plurality of MONOS type memory cells formed on fins are arranged, source regions formed on the plurality of fins arranged in a short direction of the fin are electrically connected to each other by one epitaxial layer straddling the fins.
