Abstract:
A semiconductor storage device comprising a static random access memory cell which comprises a first driver transistor, a first load element, and a first access transistor which are connected to each other through a first storage node, and a second driver transistor, a second load element, and a second access transistor which are connected to each other through a second storage node, said first driver transistor having a first gate electrode connected to said second storage node and said second driver transistor having a second gate electrode connected to said first storage node,said semiconductor storage device further comprising a first protection film formed to completely cover part of said first gate electrode with respect to a direction in which said first gate electrode extends, wherein part of said first gate electrode which is not covered by said first protection film has a structure in which a first semiconductor layer and a first metal-semiconductor compound layer are stacked in this order on a first gate insulating film, and the part of said first gate electrode which is covered by said first protection film has a structure in which said first semiconductor layer is formed on said first gate insulating film and said first metal-semiconductor compound layer is not formed on said first semiconductor layer.
