Claim 15:
16. A semiconductor device, comprising:
nanosheets;
a gate electrode surrounding the nanosheets;
spacers on sidewalls of the gate electrode;
a capping structure on the gate electrode and the spacers, the capping structure including a first capping pattern and a second capping pattern, the second capping pattern being on the first capping pattern; and
an interlayer insulating film surrounding sidewalls of each of the spacers and sidewalls of the capping structure,
wherein the gate electrode includes a gate insulating film, a metal film, and a filling film on the sidewalls of the spacers,
wherein the filling film includes a seam structure, and
wherein an uppermost surface of the filling film is on a same plane as an uppermost surface of the spacers.
