  • Patent number: 10056262
    Abstract: In an integrated-circuit memory, performance is increased by reducing an electrical contact resistance between a metal layer and an upper poly layer (a control gate poly). The electrical contact resistance is reduced by increasing the thickness of a silicide layer between the metal layer and the upper poly layer. The memory has a memory cell region and a non-memory cell region. The thickness of the silicide layer is typically restricted by consideration of integrated-circuit fabrication geometry for each memory cell not to exceed a predetermined aspect ratio. The present implementation allows independent optimization of the thickness of silicide layer in the memory cells region and the non-memory cell region. In particular, in the non-memory cell region, a thicker silicide layer significantly improves the contact resistance of a slit contact for components having the upper poly layer in contact with a lower poly layer (a floating gate poly).

  • Patent number: 8875214
    Abstract: In a television, which can be connected to a portable information terminal, it is possible to display video based on the data of a multimedia file stored on a storage medium even in cases where there is no built-in decoder. In cases where a TV itself does not possess a decoder which can decode the data of a multimedia file selected by the user from the multimedia files stored on the USB memory, the CPU of the TV transmits to a smartphone the data of the selected multimedia file and a decoding request command to request that the data be decoded, thus receiving a video signal and/or an audio signal obtained by various types of decoders of the smartphone. Consequently, the CPU of the TV can output video and/or audio to a display unit and a speaker on the basis of the data of the selected multimedia file.

  • Publication number: 20140302646
    Abstract: A performance and reliability of a semiconductor device are improved. On a semiconductor substrate, a gate electrode for a first MISFET and a dummy gate electrode for a second MISFET are formed, and then, an insulating film is partially formed on the gate electrode. Then, on the semiconductor substrate, an insulating film is formed so as to cover the dummy gate electrode, the gate electrode and other insulating film. Then, the dummy gate electrode is exposed by polishing the insulating film. In this polishing, the insulating film is polished under a condition that a polishing speed of the other insulating film is smaller than a polishing speed of the insulating film. Then, after the dummy gate electrode is removed, the gate electrode for the second MISFET is formed in a region where the dummy gate electrode has been removed.

The second setting component sets a channel number corresponding to the subset of the specific number of the sub-channels based on a second operation input. The extraction component extracts the program information corresponding to the subset of the specific number of the sub-channels set by the second setting component. The recording execution component records the program information to the program information memory component.
