    摘要: A CMP process is provided. A first polishing process on a wafer is performed using a first hard polishing pad with a first slurry. Then, a buffering process on the wafer is performed using a soft polishing pad with a cleaning agent to buffer the pH value in the first polishing process and to remove at least portion of the first slurry and the cleaning agent by the contact with the first soft polishing pad simultaneously. Thereafter, a second polishing process on the wafer is performed using a second hard polishing pad with a second slurry such that the pH value after the buffering process is between the pH value in the first polishing process and the pH value in the second polishing process. The method can avoid the scratch issue of wafer surface by particles resulting from pH shock and cross contamination.

    摘要: A method for cleaning a surface is disclosed. First, a substrate including Cu and a barrier layer is provided. Second, a first chemical mechanical polishing procedure is performed on the substrate. Then, a second chemical mechanical polishing procedure is performed on the barrier layer. The second chemical mechanical polishing procedure includes performing a main chemical mechanical polishing procedure to partially remove the barrier layer and performing a chemical buffing procedure on the substrate using a chemical solution which has a pH value of about 6 to about 8 to remove residues on the substrate after the main chemical mechanical polishing procedure. Later, a water rinsing procedure is performed on the substrate. Afterwards, a post clean procedure is performed on the substrate after the second chemical mechanical polishing procedure.

    摘要: A chemical mechanical polishing (CMP) process at least includes a polishing step and an ex-situ conditioning step, and the ex-situ conditioning step must be immediately performed after the polishing step. Therefore, it can save the process time. Furthermore, when applying to a CMP apparatus with several polishing regions, it can integrate these polishing regions having different polishing time in order to shorten total manufacturing time, thereby improving throughput.

    摘要: A method of removing an insulating layer on a substrate is described, including a first CMP process and a second CMP process performed in sequence, wherein the polishing slurry used in the first CMP process and that used in the second CMP process have substantially the same pH value that exceeds 7.0. A cleaning step is conducted between the first and the second CMP processes to remove a specific substance which would otherwise cause undesired particles to form in the second CMP process.
