Abstract

A columnar resistor and a method of laser trimming for manufacturing the same are provided. The columnar resistor includes a resistance layer disposed on the surface of a columnar substrate and the resistive layer includes a resistance determining area, a first resistance adjustment area, and a second resistance adjustment area. The resistance determining area is configured to form a first laser-trimming line and achieve a first resistance value by a first laser-trimming. The first resistance adjustment area is configured to form a second laser-trimming line and achieve a second resistance value by a second laser-trimming. The resistance value is precisely adjusted by two laser-trimming processes of the resistive layer, thereby improving the stability of product manufacturing.
