A copper foil with a resistance layer of the present invention comprises a copper foil on one surface of which a metal layer or alloy layer is formed from which a resistance element is to be formed, the surface of the metal layer or alloy layer being subjected to a roughening treatment with nickel particles. A method of production of a copper foil with a resistance layer of the present invention comprises: forming a resistance layer of phosphorus-containing nickel on a matte surface of an electrodeposited copper foil having crystals comprised of columnar crystal grains wherein a foundation of the matte surface is within a range of 2.5 to 6.5 μm in terms of Rz value prescribed in JIS-B-0601; and performing roughening treatment to a surface of the resistance layer with nickel particles wherein a roughness is within a range of 4.5 to 8.5 μm in terms of Rz value prescribed in JIS-B-0601. The alloy layer is for example formed from phosphorus-containing nickel.

摘要:
An arithmetic circuit, which is retained by each pixel in a conventional image sensor, is shared by each column. Signal processing circuits of different configurations are provided on signal transmission paths in an upward direction and a downward direction of a vertical signal line for extracting an image signal from each pixel, whereby image output processing and arithmetic processing are performed completely separately by the different circuit blocks. Thus, image quality of an actual image is improved and optimum design for arithmetic processing is made possible. Specifically, an I-V converter circuit unit, a CDS circuit unit and the like are provided on the image output side. A current mirror circuit unit, an analog memory array unit, a comparator unit, a bias circuit unit, a data latch unit, an output data bus unit and the like are provided on the arithmetic processing side.
