ABSTRACT:
A method for manufacturing a semiconductor resistor includes forming a well region in a semiconductor substrate, with the well region serving as a resistive region, forming a pair of contact regions spaced apart from each other in the well region, and forming a diffusion region in an intermediate portion between the pair of contact regions on a surface of the well region. The diffusion region is configured to adjust resistance and temperature dependence of the semiconductor resistor.
