Abstract:
1. A semiconductor integrated circuit device comprising: first MISFETs of a first conductive type each having a first gate insulating film, a first gate electrode and a source and drain region; second MISFETs of the first conductive type each having a second gate insulating film, a second gate electrode and a source and drain region, wherein a thickness of the first gate insulating film is thinner than a thickness of the second gate insulating film; a logic circuit including the first MISFET; a memory including the first MISFET; and a fuse circuit including the second MISFET and a fuse element, wherein at least one of relieving, function selection and trimming is executed by a breakdown of the fuse element, wherein the fuse element includes an insulating film having a thickness equal to a thickness of the first gate insulating film, and wherein the breakdown of the fuse element is performed by a breakdown of the insulating film of the fuse element.
