Title:
SEMICONDUCTOR DEVICE
Document Type and Number:
WIPO Patent Application WO/2012/137590
Kind Code:
A1
Abstract:
This semiconductor device formed on a main surface of a substrate is provided with: an electric circuit (2) that includes a first resistor (VR2); second and third resistors (RA, RB); and a correcting unit (10). The electric circuit (2) changes the characteristics thereof, corresponding to a resistance value of the first resistor (VR2). The second and the third resistors (RA, RB) are formed of a material same as that of the first resistor (VR2), and one of the resistors is provided at a position closer to the center of the main surface than a position where the other resistor is provided. On the basis of change quantities of resistance values of the second and the third resistors (RA, RB), the correcting unit (10) generates correction signals (13) for correcting the characteristics of the electric circuit (2).
