Abstract:
To provide a semiconductor device having improved reliability by relaxing the unevenness of the injection distribution of electrons and holes into a charge accumulation film attributable to the shape of the fin of a MONOS memory comprised of a fin transistor. Of a memory gate electrode configuring a memory cell formed above a fin, a portion contiguous to an ONO film that covers the upper surface of the fin and a portion contiguous to the ONO film that covers the side surface of the fin are made of electrode materials different in work function, respectively, and the boundary surface between them is located below the upper surface of the fin.

Claim (Index 1):
A semiconductor device comprising:\n a semiconductor substrate; a protruding semiconductor layer which is a portion of the semiconductor substrate, protrudes from a main surface of the semiconductor substrate, and extends in a first direction along the main surface; a gate electrode adjacent to an upper surface and a side surface of the protruding semiconductor layer via an insulating film including a charge accumulation film and extending in a second direction crossing the first direction; and a source region and a drain region sandwiching the gate electrode therebetween in the first direction of the protruding semiconductor layer, wherein the gate electrode has a first gate electrode adjacent to the side surface of the protruding semiconductor layer via the insulating film and a second gate electrode adjacent to the upper surface of the protruding semiconductor layer via the insulating film, wherein the first gate electrode and the second gate electrode include respectively different electrode materials, and wherein a boundary surface between the first gate electrode and the second gate electrode lies on the side of the main surface with respect to the upper surface of the protruding semiconductor layer.
