    摘要: A poly opening polish process includes the following steps. A semi-finished semiconductor component is provided. The semi-finished semiconductor component includes a substrate, a gate disposed on the substrate, and a dielectric layer disposed on the substrate and covering the gate. A first polishing process is applied onto the dielectric layer. A second polishing process is applied to the gate. The second polishing process utilizes a wetting solution including a water soluble polymer surfactant, an alkaline compound and water. The poly opening polish process can effectively remove an oxide residue formed in the chemical mechanical polish, thereby improving the performance of the integrated circuit and reducing the production cost of the integrated circuit.

    摘要: A semiconductor process includes the following steps. A first gate structure and a second gate structure are formed on a substrate, wherein the top of the first gate structure includes a cap layer, so that the vertical height of the first gate structure is higher than the vertical height of the second gate structure. An interdielectric layer is formed on the substrate. A first chemical mechanical polishing process is performed to expose the top surface of the cap layer. A second chemical mechanical polishing process is performed to expose the top surface of the second gate structure or an etching process is performed to remove the interdielectric layer located on the second gate structure. A second chemical mechanical polishing process is then performed to remove the cap layer.

    摘要: A semiconductor process includes the following steps. An interdielectric layer is formed on a substrate and the interdielectric layer has a first recess and a second recess. A metal layer is formed to cover the surface of the interdielectric layer, the first recess and the second recess. Partially fills a sacrificed material into the first recess and the second recess so that a portion of the metal layer in each of the recesses is respectively covered. The uncovered metal layer in each of the recesses is removed. The sacrificed material is removed. An etching process is performed to remove the remaining metal layer in the first recess and reserve the remaining metal layer in the second recess.
