摘要：
The present invention provides a method of manufacturing semiconductor device having metal gates. First, a substrate is provided. A first conductive type transistor having a first sacrifice gate and a second conductive type transistor having a second sacrifice gate are disposed on the substrate. The first sacrifice gate is removed to form a first trench. Then, a first metal layer is formed in the first trench. The second sacrifice gate is removed to form a second trench. Next, a second metal layer is formed in the first trench and the second trench. Lastly, a third metal layer is formed on the second metal layer wherein the third metal layer is filled into the first trench and the second trench.
