    摘要: A method of manufacturing a resistor integrated with a transistor having metal gate includes providing a substrate having a transistor region and a resistor region defined thereon, a transistor is positioned in the transistor region and a resistor is positioned in the resistor region; forming a dielectric layer exposing tops of the transistor and the resistor on the substrate; performing a first etching process to remove portions of the resistor to form two first trenches respectively at two opposite ends of the resistor; forming a patterned protecting layer in the resistor region; performing a second etching process to remove a dummy gate of the transistor to form a second trench in the transistor region; and forming a metal layer filling the first trenches and the second trench.

    摘要: A metal gate process includes the following steps. An isolating layer on a substrate is provided, where the isolating layer has a first recess and a second recess. A first metal layer covering the first recess and the second recess is formed. A material is filled in the first recess but exposing a top part of the first recess. The first metal layer in the top part of the first recess and in the second recess is simultaneously removed. The material is removed. A second metal layer and a metal gate layer in the first recess and the second recess are sequentially filled.
