    Abstract: A method for establishing robust prediction model is adapted for solving the problem that the conventional prediction model cannot generate stable and credible results with missing data. The method of the present invention includes the following steps: obtaining pre-established single-modality standard models respectively based on each type of modalities from samples; extracting modality sets each having the same modality types from the samples to establish corresponding multi-modalities standard models; extracting multiple combinations of the modality sets from the samples having complete modalities to be training data, wherein the multiple combinations of the modality sets can be classified into single-modality, multi-modalities and complete-modalities; inputting said training data into a to-be trained prediction model, and modifying the prediction model by said single-modality standard models and said multi-modalities standard models to obtain a well-trained prediction model.

  • 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.

  • Patent number: 11804706
    Abstract: An over-voltage protection circuit includes an over-voltage detection circuit, a voltage generator and a switch for providing over-voltage protection between two pins of a USB Type-C port. The over-voltage detection circuit provides an over-voltage signal according to the level of the second pin. The switch includes a first end coupled to the first pin, a second end coupled to the second pin and a control end coupled to a control signal. When the over-voltage signal does not indicate an over-voltage occurrence at the second pin, the voltage generator provides the control signal having a first level for operating the switch in a first region. When the over-voltage signal indicates an over-voltage occurrence at the second pin, the voltage generator adjusts the control signal to a second level for cutting off the switch. The switch operates in a second region after the over-voltage occurrence and before the switch is cut off.

  • 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.
