摘要: An object of the present invention is to improve in-plane uniformity in polishing in a polishing device.
A temperature adjusting device for adjusting temperature of a rotating polishing pad comprises: a heat conductor that can contact with a top face of the polishing pad; an arm for holding the heat conductor above the polishing pad; column members formed to stand on a top face of the heat conductor, comprising an upstream-side column member and a downstream-side column member arranged at a position at an upstream/downstream side of rotation of the polishing pad; and overhung members extending, from the upstream-side column member and the downstream-side column member, in directions that are parallel to the top face of the heat conductor; wherein the overhung members can contact with a top face of the arm.-

摘要: A method for removing material from a substrate includes dispensing an abrasive slurry on a polishing pad, storing an indication of a relative charge on the abrasive agent, contacting a surface of a substrate to the polishing pad in the presence of the slurry, generating relative motion between the substrate and the polishing pad, measuring a removal rate for the substrate, comparing a the measured removal rate to a target removal rate and determining whether to increase or decrease the removal rate based on the comparison, determining whether to increase or decrease a temperature of an interface between the polishing pad and the substrate based on the indication of the relative charge of the abrasive agent and on whether to increase or decrease the removal rate, and controlling a temperature of the interface as determined to modify the removal rate.

摘要: In some embodiments, the present disclosure relates to a chemical mechanical planarization (CMP) tool. The CMP tool includes a carrier and a malleable membrane coupled to the carrier and having a lower surface facing away from the carrier. The lower surface of the malleable membrane includes a first malleable material within a central region of the lower surface and a second malleable material within a peripheral region of the lower surface, which surrounds the central region. The first malleable material provides the central region of the lower surface with a first stiffness and the second malleable material provides the peripheral region of the lower surface with a second stiffness that is different than the first stiffness.

摘要: The present application relates to a pad-temperature regulating apparatus for regulating a temperature of a surface of a polishing pad. The pad-temperature regulating apparatus includes a pad-contact member, a supply system for supplying a heating liquid and a cooling liquid into the pad contact member, a pad-temperature measuring device for measuring the temperature of the surface of the polishing pad, and a controller for performing a PID control of manipulated variables of a first flow control valve and a second flow control valve. The controller includes a memory in which a learned model constructed to maintain a temperature behavior curve, created based on measured values of the pad-temperature measuring device, within a predetermined allowable range, is stored; and a processing device which inputs at least one temperature behavior parameter to the learned model, and performs a calculation to output a change value of PID parameter for the PID control.
