description | A manufacturing method for a resistor integrated with a transistor having metal gate includes providing a substrate having a transistor region and a resistor region defined thereon, respectively forming a transistor having a dummy gate in the transistor region and a resistor in the resistor region, removing the dummy gate and portions of the resistor to form a first trench in the transistor and two second trenches in the resistor, forming at least a high-k gate dielectric layer in the first trench and the second trenches, and forming a metal gate in the first trench and metal structures respectively in the second trenches. |
