A cathode n+-type semiconductor region and an anode p-type semiconductor region are formed in the semiconductor substrate and the second trench is formed so as to surround the n+-type semiconductor region in a planar view. A part of the anode p-type semiconductor region is formed directly below the n+-type semiconductor region, so that a PN junction is formed between the part of the anode p-type semiconductor region and the n+-type semiconductor region. Thereby a diode is formed. The dummy gate electrode is electrically coupled to one of an anode and a cathode.Type: GrantFiled: February 13, 2013Date of Patent: August 12, 2014Assignee: Renesas Electronics CorporationInventors: Hiroaki Katou, Taro Moriya, Hiroyoshi Kudou, Satoshi Uchiya

Patent number: 8779516Abstract: A second conduction-type MIS transistor in which a source is coupled to a second power source over the surface of a first conduction-type well and a drain is coupled to the open-drain signal terminal is provided. A second conduction-type first region is provided at both sides of the MIS transistor in parallel with a direction where the electric current of the MIS transistor flows and coupled to the open-drain signal terminal. The whole these components are surrounded by a first conduction-type guard ring coupled to the second power source and the outside surrounded by the first conduction-type guard ring is further surrounded by a second conduction-type guard ring coupled to a first power source. Thereby, the semiconductor device is capable of achieving ESD protection of an open-drain signal terminal having a small area and not providing a protection element between power source terminals.Type: GrantFiled: July 22, 2011Date of Patent: July 15, 2014Assignee: Renesas Electronics CorporationInventor: Toshikatsu Kawachi

Patent number: 8779550Abstract: An analog floating-gate electrode in an integrated circuit, and method of fabricating the same, in which trapped charge can be stored for long durations. The analog floating-gate electrode is formed in a polycrystalline silicon gate level, and includes portions serving as a transistor gate electrode, a plate of a metal-to-poly storage capacitor, and a plate of poly-to-active tunneling capacitors. A silicide-block film comprised of a layer of silicon dioxide underlying a top layer of silicon nitride blocks the formation of silicide cladding on the electrode, while other polysilicon structures in the integrated circuit, such as polysilicon-to-metal capacitors, are silicide-clad. Following silicidation, a capacitor dielectric is deposited over the remaining polysilicon structures, followed by formation of an upper metal plate.Type: GrantFiled: June 27, 2012Date of Patent: July 15, 2014Assignee: Texas Instruments IncorporatedInventors: Kaiping Liu, Amitava Chatterjee, Imran Mahmood Khan
