Patent ID: 8866120

Claim:
A semiconductor integrated circuit device, comprising: a first interlayer insulating film formed over a semiconductor substrate; a first plug and a second plug formed in the first interlayer insulating film; a chalcogenide material film formed over the first interlayer insulating film and over the first plug such that a bottom surface of the chalcogenide material film is located over the first plug; an electrode formed over the chalcogenide material film; an insulating film formed over the electrode, over the first interlayer insulating film and over the second plug in order to cover a side surface of the chalcogenide material film, and formed of a different material from the first interlayer insulating film; a second interlayer insulating film formed over the insulating film and formed of a different material from the insulating film; a third plug formed in the second interlayer insulating film and in the insulating film, and connected to the electrode; and a fourth plug formed in the second interlayer insulating film and in the insulating film, and directly connected to the second plug.
