Abstract
A semiconductor device 100 includes: a silicon substrate 102; a first gate 114a including a gate electrode 108 formed on the silicon substrate 102 and sidewalls 112 formed on the sidewalls of the gate electrode 108; a silicide layer 132 formed lateral to the sidewalls 112 of the first gate 114a on a surface of the silicon substrate 102; and a contact 164 which overlaps at least partially in plan view with the first gate 114a and reaches to the silicide layer 132 of the surface of the silicon substrate 102; wherein an insulator film is located between the contact 164 and the gate electrode 108 of the first gate 114a.
