Abstract
PURPOSE:To improve a device of this design in a noise resistant property and make a bus reduce in a line width so as to decrease the area by a method wherein a bypass capacitor is provided just under a power sourceground supply bus in such a range that does not exceed the width of the bus. CONSTITUTION:Conductive materials 10i and 10j covered with an insulator 14 are provided just under a power source supply bus 4c and a ground supply bus 5c and connected with the buses through through-holes 11a and 11b respectively. Moreover, these are formed smaller than the line width of the bus provided to the space where functional element is not to be formed. Besides being locally provided in such an arrangement as mentioned above, a bypass capacitor functions effectively as well even if it is provided to the whole face of the power source-ground supply bus or it is formed taking advantage of an input capacitance of a transistor or the like, so that a noise resistant property can be improved and a occupying area can be reduced through the bypass capacitor provided or formed in the above mentioned manner.
