Abstract

PURPOSE:To prevent a value of diffusion resistance from fluctuating, by identifying an area ratio of a conductive film on a specific resistance. CONSTITUTION:Electrodes 6 made of Al films are partially extended to cover resistances 3. Al wirings 7 cross the resistance on one side. The resistance R1 on a left side and the resistance R2 on a right side are formed so that areas of the resistance parts not covered with the Af films are made identical to each other. If an interval between the electrode 5 and the Al wirings 7 which cross the resistance is assumed (a) to (c) in the resistance R1 on the left side, a distance between the Al electrodes 5 and 6 becomes a+b+c in the resistance R2 on the right side. When cover ratios are thus identified between the resistances R1 and R2 which need paired performance in their resistance R ratios, the resistance ratios between paired resistances can be prevented from much fluctuating.
