Abstract: Chip moving device is provided. The chip moving device includes a base, including a mounting portion that includes an end surface and an assembly cavity extending in a horizontal direction and penetrating through the end surface, the end surface being arranged with a limiting component; an adsorption part, extending in a vertical direction and confined by the limiting component; and a clamping component, arranged in the assembly cavity and including an end extending out of the end surface of the mounting portion, the clamping component being configured to be telescopic in the horizontal direction, and provide the adsorption part with a clamping force in the horizontal direction when the clamping component is extended or contracted.

Abstract: A heating structure and a wafer test device are provided. The heating structure includes: a heating base, provided with a heating element inside the heating base; a mounting component, disposed above the heat base and including a plurality of mounting stations arranged at intervals; and a plurality of insulating thermo-conductive blocks. Each of the plurality of insulating thermo-conductive blocks is disposed at one corresponding mounting station of the plurality of mounting stations and protrudes from the mounting component for contacting a clamp of the wafer test device.

Abstract: A wafer-level semiconductor high-voltage reliability test fixture is provided. The test fixture includes: a first insulation plate, a first circuit board, and a second insulation plate. A target object is disposed between the first circuit board and the second insulation plate. A side of the first circuit board facing the target object is provided with a probe holder including probes. The first circuit board is connected to the target object through the probes such that a high-voltage electrical signal is transmitted to the target object when the high-voltage electrical signal is applied to the first circuit board. The first insulation plate and the second insulation plate isolate the high-voltage electrical signal from the outside world, and the probes also transmit test electrical signals to the target object and transmit feedback signals to the first circuit board when the test electrical signals are applied to the first circuit board.

Abstract: The present disclosure includes a die test pressing-down apparatus and a formation method. The die test pressing-down apparatus includes a support frame capable of moving along a vertical direction; and a pressing-down block installed on the support frame. A part to-be-pressed is disposed directly below the pressing-down block. The pressing-down block is connected to the support frame through an installation plate; a strip-shaped through hole is formed at an upper surface of the support frame; a first protruding strip is at each lower portion of two opposite inner walls of the strip-shaped through hole; a corresponding second protruding strip is at each upper portion of two opposite side surfaces of the installation plate; and a side of a strip-shaped block is fixedly connected to the upper surface of the support frame, and another side of the strip-shaped block is connected to the second protruding strip through at least two springs.

Abstract: The present disclosure includes an adaptive die test socket and a formation method. The die test socket includes an upper test socket and a lower test socket disposed directly below the upper test socket. The upper test socket is connected to a support frame; a strip-shaped through hole is formed on an upper surface of the support frame; a first protruding strip is at each of lower portions of two opposite inner walls of the strip-shaped through hole; a corresponding second protruding strip is at each of upper portions of two opposite side surfaces of the installation plate; and a side of a strip-shaped block is fixedly connected to the upper surface of the support frame, and another side of the strip-shaped block extends to directly above the second protruding strip and is connected to the second protruding strip through at least two springs.
