Abstract

PURPOSE:To obtain a constant output at all times despite the variation of temperature by a method wherein a pattern is provided in such a manner that a difference in variation of resistance caused by the difference between the shapes of the pattern is minimized. CONSTITUTION:A region of a diffusion layer with low resistance is formed in each of the other facing two resistance layers and the other two resistance layers are allowed to generate the same variation as that of resistance due to the distortion of two of the resistance layers. In this case, for instance, in the substantially central portions of resistance layers other than resistance layers 4C, 4D where diffusion layers 6C, 7C with low resistance have been formed, i.e., resistance layers 4A, 4B, diffusion layers 10A, 10B having roughly the same areas as those of 6C, 7C are provided. If these diffusion layers are bridged, their facing sides become almost electrically symmetrical. For this reason, the output characteristics due to the variation of temperature are improved to about 1/10 in comparison with conventional ones.
