    摘要: A method of manufacturing the semiconductor device having a dual fully-silicided gate includes the following steps. A substrate having a first transistor and a second transistor formed thereon is provided, wherein the first transistor includes a first gate and a first source/drain and the second transistor includes a second gate and a second source/drain. The gate height of the first gate is different from that of the second gate. A first silicidation process is performed to respectively transform the first gate and the second gate into a first silicided gate and a second silicided gate simultaneously, wherein the material of the first silicided gate is different from that of the second silicided gate.

    摘要: A method for forming a fully silicided gate is disclosed. A gate structure of a transistor device is provided on a substrate. A mask layer is spin-on coated over the substrate to cover the gate structure and source/drain regions of the transistor device. The mask layer is etched back to expose a silicon layer of the gate structure. The silicon layer of the gate structure is then fully silicided. The mask layer is then removed from the substrate to expose the source/drain regions. The source/drain regions are finally silicided.
