  • Patent number: 9324883
    Abstract: In a power feeding region of a memory cell (MC) in which a sidewall-shaped memory gate electrode (MG) of a memory nMIS (Qnm) is provided by self alignment on a side surface of a selection gate electrode (CG) of a selection nMIS (Qnc) via an insulating film, a plug (PM) which supplies a voltage to the memory gate electrode (MG) is embedded in a contact hole (CM) formed in an interlayer insulating film (9) formed on the memory gate electrode (MG) and is electrically connected to the memory gate electrode (MG). Since a cap insulating film (CAP) is formed on an upper surface of the selection gate electrode (CG), the electrical conduction between the plug (PM) and the selection gate electrode (CG) can be prevented.

  • Patent number: 9299665
    Abstract: A structure fabrication method. An integrated circuit that includes N chip electric pads is bonded to a top side of an interposing shield that includes N electric conductors. N is at least 2. The interposing shield includes a shield material that includes a first semiconductor material. A bottom side of the interposing shield is polished, which exposes the N electric conductors to a surrounding ambient. The bonding includes bonding the integrated circuit to the top side of the interposing shield such that the N chip electric pads are in electrical contact and direct physical contact with corresponding electrical pads of the N electric conductors. The shield material covers the N electric conductors in a manner that the N electric conductors are not exposed to the surrounding ambient. The polishing removes a sufficient amount of the shield material to expose the N electric conductors to the surrounding ambient.
