Abstract
An IC structure includes a resistor circuit and a transistor. The resistor circuit includes a first metal resistor strip over a semiconductor substrate, and a first metal line and a second metal line extending on a same level height above the first metal resistor strip. The first metal resistor strip is a dummy gate. Both the first metal line and the second metal line overlap and are electrically connected to the first metal resistor strip. The transistor includes a metal gate strip on a same level height as the first metal strip and extends in parallel with the first metal resistor strip.
