    摘要: The present disclosure relates to a two-phase cleaning element that enhances polishing pad cleaning so as to prevent wafer scratches and contamination in chemical mechanical polishing (CMP) processes. In some embodiments, the two-phase pad cleaning element comprises a first cleaning element and a second cleaning element configured to successively operate upon a section of a CMP polishing pad. The first cleaning element comprises a megasonic cleaning jet configured to utilize cavitation energy to dislodge particles embedded in the CMP polishing pad without damaging the surface of the polishing pad. The second cleaning element is configured to apply a high pressure mist, comprising two fluids, to remove by-products from the CMP polishing pad. By using megasonic cleaning to dislodge embedded particles a two-fluid mist to flush away by-products (e.g., including the dislodged embedded particles), the two-phase pad cleaning element enhances polishing pad cleaning.

    摘要: To provide improved planarization, techniques in accordance with this disclosure include a CMP station that includes a plurality of concentric temperature control elements arranged over a number of concentric to-be-polished wafer surfaces. During polishing, a wafer surface planarity sensor monitors relative heights of the concentric to-be-polished wafer surfaces, and adjusts the temperatures of the concentric temperature control elements to provide an extremely well planarized wafer surface. Other systems and methods are also disclosed.

    摘要: Some embodiments relate to a chemical mechanical polishing (CMP) system. The CMP system includes a polishing pad having a polishing surface, and a wafer carrier to retain a wafer proximate to the polishing surface during polishing. A motor assembly rotates the polishing pad and concurrently rotates the wafer during polishing of the wafer. A conditioning disk has a conditioning surface that is in frictional engagement with the polishing surface during polishing. A torque measurement element measures a torque exerted by the motor assembly during polishing. A condition surface analyzer determines a surface condition of the conditioning surface or the polishing surface based on the measured torque. Other systems and methods are also disclosed.
