Abstract: A semiconductor device includes lower gate electrodes placed on a substrate and spaced apart from one another; upper gate electrodes placed over the lower gate electrodes and spaced apart from one another; an R-type pad extending from one end of at least one electrode among the lower gate electrodes or the upper gate electrodes and having a greater thickness than the lower gate electrode or upper gate electrode connected to the R-type pad; and a P-type pad extending from one end of at least one electrode to which the R-type pad is not connected among the lower gate electrodes or the upper gate electrodes and having a different thickness than the R-type pad, wherein the P-type pad includes a first pad connected to an uppermost lower gate electrode among the lower gate electrodes.
