  • Patent number: 9780232
    Abstract: To enhance the performance of a semiconductor device. In a method for manufacturing a semiconductor device, a metal film is formed over a semiconductor substrate having an insulating film formed on a surface thereof, and then the metal film is removed in a memory cell region, whereas, in a part of a peripheral circuit region, the metal film is left. Next, a silicon film is formed over the semiconductor substrate, then the silicon film is patterned in the memory cell region, and, in the peripheral circuit region, the silicon film is left so that an outer peripheral portion of the remaining metal film is covered with the silicon film. Subsequently, in the peripheral circuit region, the silicon film, the metal film, and the insulating film are patterned for forming an insulating film portion formed of the insulating film, a metal film portion formed of the metal film, and a conductive film portion formed of the silicon film.

  • Publication number: 20170195881
    Abstract: In order to enable a user's portable terminal to be authenticated by a method which is easy for the user, a control device of this information processing system uses terminal information transmitted from a portable terminal and containing a first identifier to generate a second identifier, which is returned to the portable terminal. The portable terminal presents the obtained second identifier in a visual manner. When the control device detects, on the basis of a photographic image from an imaging device which photographs a predetermined imaging area, that the generated second identifier has been presented visually by the portable terminal, the control device authenticates that portable terminal.

  • Patent number: 9379150
    Abstract: The present invention improves the performance of an image sensor. In a planar view, fluorine is introduced into a part overlapping with a channel region in a gate electrode GE1 of an amplification transistor and is not introduced into the interior of a semiconductor substrate 1S. Concretely as shown in FIG. 20, a resist film FR1 is patterned in the manner of opening the part planarly overlapping with the channel region in the gate electrode GE1. Then fluorine is injected into the interior of the gate electrode GE1 exposed from an opening OP1 by an ion implantation method using the resist film FR1 in which the opening OP1 is formed as a mask.

    Abstract: The performance of a semiconductor device is improved by preventing 1/f noise from being generated in a peripheral transistor, in the case where the occupation area of photodiodes, which are included in each of a plurality of pixels that form an image pickup device, is expanded. In the semiconductor device, the gate electrode of an amplification transistor is formed by both a gate electrode part over an active region and a large width part that covers the boundary between the active region and an element isolation region and the active region near the boundary and that has a gate length larger than that of the gate electrode part.

  • Patent number: 9287259
    Abstract: MISFETs after the 32 nm technology node have a High-k gate insulating film and a metal gate electrode. Such MISFETs have the problem that the absolute value of the threshold voltage of n-MISFET and p-MISFET inevitably increases by the subsequent high temperature heat treatment. The threshold voltage is therefore controlled by forming various threshold voltage adjusting metal films on a High-k gate insulating film and introducing a film component from them into the High-k gate insulating film. The present inventors have however revealed that lanthanum or the like introduced into the High-k gate insulating film of the n-MISFET is likely to transfer to the STI region by the subsequent heat treatment. The semiconductor integrated circuit device according to the present invention is provided with an N channel threshold voltage adjusting element outward diffusion preventing region in the surface portion of the element isolation region below and at the periphery of the gate stack of the n-MISFET.
