Provided is a semiconductor device (1) in which a contact (C5a) is provided so as to extend to a first selection gate electrode (G2a) from the top of a contact installation structure (10a) having the same configuration as a memory gate structure (4a). Accordingly, a conventional mounting section (102b) mounting the top of the memory gate structure (110) is not formed (fig. 13), and thus the distance to an upper-layer wiring layer can be shortened, the aspect ratio can be reduced, and, as a result, an increase in the contact resistance value can be inhibited. Furthermore, the conventional mounting section (102b) mounting the top of the memory gate structure (110) is not formed, and thus the contact installation structure (10a) and the upper-layer wiring layer can be kept apart, and, as a result, contact failure with the upper-layer wiring layer can be inhibited. Also provided is a production method for said semiconductor device.
