  • Publication number: 20240066664
    Abstract: The present disclosure relates to a pad surface cleaning system to be used with a conditioning module to condition a polishing surface of a polishing pad. The pad surface cleaning system may be used to spray the polishing surface with a high-pressure fluid spray to loosen debris from the polishing surface. The pad surface cleaning system may also be used to remove the loosened debris. Further, the pad surface cleaning system may isolate a conditioning disk from a polishing fluid to protect the conditioning disk from reacting with the polishing fluid.

  • Patent number: 11819976
    Abstract: Methods and apparatuses for dispensing polishing fluids onto a polishing pad within a chemical mechanical polishing (CMP) system are disclosed herein. In particular, embodiments herein relate to a CMP polishing method including urging a substrate against a surface of a pad of a polishing system using a carrier assembly. A fluid is dispensed onto the pad from a fluid delivery assembly at a variable flow rate and a first flow rate of the variable flow rate is pulsed at a frequency and a duty cycle. The frequency refers to a number of pulses of the fluid at the first flow rate per rotation of the pad. The term duty cycle refers to a percentage of the pad exposed to fluid per rotation of the pad. The carrier assembly is translated across a surface of the pad while rotating the carrier assembly about a rotational axis.

  • Publication number: 20230299602
    Abstract: A controller for managing a battery pack includes: a detection terminal, for transmitting an enable signal when values of battery parameters for the battery pack satisfy a sleep condition, where the enable signal enables the detection circuit to detect whether the battery pack is connected to a load and whether the battery pack is connected to the charger; and a receiving terminal, for receiving a detection result transmitted by the detection circuit. The detection result indicates whether the battery pack is connected to at least one of the load and charger. The controller controls the battery pack to enter a sleep mode of the sleep modes based on the detection result. The controller also includes a control terminal, for transmitting a control signal to control an on/off state of a charging switch and/or a discharging switch. The control signal is generated by the controller based on the detection result.

  • Publication number: 20230238266
    Abstract: An apparatus includes a substrate holder, a first actuator to rotate the substrate holder, a second actuator to move the substrate holder linearly, a first sensor to generate one or more first measurements or images of the substrate, a second sensor to generate one or more second measurements of target positions on the substrate, and a processing device. The processing device estimates a position of the substrate on the substrate holder and causes the first actuator to rotate the substrate holder about a first axis. The rotation causes an offset between a field of view of the second sensor and a target position on the substrate due to the substrate not being centered on the substrate holder. The processing device causes the second actuator to move the substrate holder linearly along a second axis to correct the offset. The processing device determines a profile across a surface of the substrate based on the one or more second measurements of the target positions.
