    Abstract: A heterogeneous integration detecting method and a heterogeneous integration detecting apparatus are provided. The heterogeneous integration detecting method includes the following. Under the condition of maintaining the same relative distance between an interference objective lens and a sample, the relative posture of the interference objective lens and the sample is continuously adjusted according to the change of an image of the sample in the field of view of the interference objective lens until a first optical axis of the interference objective lens is determined to be substantially perpendicular to the surface of the sample according to the image.

  • Publication number: 20240110968
    Abstract: An inspection system includes an excitation light source, a voltage-sensing film, an illumination light source, an image capture device. The excitation light source provides an excitation beam to light-emitting diodes to generate open-circuit voltages. The voltage-sensing film is at a top side of the light-emitting diodes and includes a voltage-sensing medium layer and a first electrode layer. The first electrode layer is in the voltage-sensing medium layer to provide a gain effect of the open-circuit voltages, so that the voltage-sensing medium layer senses the open-circuit voltages, and a display of the voltage-sensing medium layer is changed with a portion or all of the open-circuit voltages. The illumination light source provides an illumination beam to the voltage-sensing film to generate a sensing image according to a display change. The image capture device is on a transmission path of the sensing image and receives the sensing image to generate an inspection result.

  • Publication number: 20230184819
    Abstract: A method for inspecting LED dies includes the following steps. First electrodes and second electrodes of LED dies to be inspected are short-circuited via a conductive layer on an inspection substrate, or an inspection bias voltage is applied between the first electrodes and the second electrodes of the LED dies. An excitation light is irradiated on the LED dies to be inspected on the inspection substrate such that the LED dies to be inspected emit a secondary light. When the first electrodes and the second electrodes of the LED dies to be inspected are open, short-circuited, and/or subjected to the inspection bias voltage, the secondary light is captured via an optical sensor. An output of the optical sensor is received via a computer and a spectrum difference of the secondary light is calculated to determine whether the LED dies are abnormal or to classify the LED dies to be inspected.
