PURPOSE:To equalize the errors of respective resistance elements in respective directions by a method wherein the arrayal directions of the respective elements are equalized in multiple input or output circuits including resistance elements in the same resistance value. CONSTITUTION:Respective elements R1, R2 of an output circuit 2 as well as the other resistance elements R3. R4 of another output circuit 3 are formed of polycrystal silicon in the same shape further to be arranged in the same direction. Thus, the resistance values of respective resistance elements R1-R4 are equalized. Through these procedures, even if the errors are differentiated in the X or Y directions due to the bending of wafers, effect of manufacturing device/ etc:, the errors in the elements R1-R4 in respective directions can be equalized. Accordingly, the precision in respective output circuits 2, 3 can be enhanced. |
