[0001] The present invention relates to the technical field of absorbance detection, and more specifically, to a semiconductor chip absorbance detection device. Background Art

[0002] Semiconductor chip absorbance detection devices play an important role in the semiconductor industry. Their main purpose is to measure the degree of light absorption of chip materials, thereby reflecting certain characteristics of the materials, such as composition, thickness, and uniformity. This is crucial for ensuring the quality and consistency of chip materials. During the production process of semiconductor chips, absorbance detection devices can be used to monitor the quality of the production line. By regularly detecting the absorbance of chips, problems in the production process, such as contamination and defects, can be promptly discovered, and corresponding measures can be taken to correct them, ensuring the yield and reliability of the products.

This technology has a light incident part and a detection part. The light incident part is opposite to the light incident port and allows the light of the light source to transmit through.

The second substrate is combined with the first substrate; and a flow cell, one end of which is connected to the light incident port, and the other end is connected to the detection port. The first substrate and the second substrate are formed of light-absorbing materials. However, this technology still has the following defects;

[0004] During the semiconductor chip absorbance detection process, the absorbance of the semiconductor chip is mainly detected by irradiating the semiconductor chip with a light beam and then knowing the light intensity after passing through the semiconductor chip. However, during the absorbance detection, due to the large number of surface points on the semiconductor chip, it is difficult to quickly switch and detect multiple semiconductor chips as needed, and it is also difficult to achieve inclined multi-point detection. Not only is the detection not comprehensive enough, but the detection efficiency is also low. Therefore, a semiconductor chip absorbance detection device is needed. Summary of the Invention

[0005] To overcome the above-mentioned defects of the prior art, the present invention provides the following technical solution: a semiconductor chip absorbance detection device, including a sleeve frame, a support frame and a socket slider. The support frame is fixed at the top of the sleeve frame. The socket slider is slidably connected inside the support frame. An inclined transformation detection component is installed at one end of the support frame; the inclined transformation detection component includes an electric cylinder fixedly installed at one end of the support frame. The outer wall of the output end of the electric cylinder is slidably connected with the support frame. The output end of the electric cylinder is fixedly connected with the socket slider; a displacement frame is fixedly installed at the bottom end of the socket slider. A guiding slide bar is slidably connected inside the displacement frame. An inclined sleeve block is fixedly installed at one end of the guiding slide bar.

A reinforcing frame is installed at the bottom end of the electric cylinder, and both the inclined guide bar and the electric cylinder are fixedly connected with the reinforcing frame.

[0007] When this technical solution is in use, the electric cylinder drives the socket slider to move to the right. At the same time, the socket slider slides to the right along the inner wall of the support frame. The displacement frame drives the two limiting rings to move to the right. The displacement frame drives the guiding slide bar to incline and move downward. The inclined sleeve block inclines and moves downward along the outer wall of the inclined guide bar. The inclined sleeve block drives the connecting frame to incline and move downward. The support frame drives the linkage screw to incline and move downward. The threaded sleeve block drives the sleeve frame bar to incline and move downward. The sleeve frame bar drives the detection light source to incline and move downward, and the other sleeve frame bar also inclines and moves downward along the detection chip.

[0008] Preferably, the displacement detection component includes a linkage screw rotatably installed inside the support frame; one end of the support frame is fixedly installed with an adjustment motor, the output end of the adjustment motor is fixedly connected to the linkage screw, two threaded sleeve blocks are threadedly connected to the outer wall of the linkage screw, and the threads on the outer wall of the linkage screw are opposite and symmetrically arranged. Both of the two threaded sleeve blocks are slidably connected to the support frame; a sleeve frame bar is fixedly connected to the bottom end of each threaded sleeve block, a detection light source is fixedly installed inside the sleeve frame bar, a photosensitive sensor is arranged on one side of the detection light source, and the photosensitive sensor is fixedly connected to the other sleeve frame bar. The adjustment motor is used to drive the linkage screw to rotate, and the outer walls of both of the two threaded sleeve blocks are smooth surfaces.

[0009] When this technical solution is in use, the adjustment motor starts to drive the linkage screw to rotate. The linkage screw drives the two threaded sleeve blocks to approach each other under the action of the thread driving force. The threaded sleeve blocks drive the sleeve frame bars to move to the right. The detection light source is located on the left side of the detection chip, and the photosensitive sensor is located on the right side of the detection chip. In this way, the detection light source and the photosensitive sensor can be positioned at the detection position of the detection chip.

[0010] Preferably, the switching detection component includes a turntable fixedly arranged below the support frame. A plurality of positioning frames are fixedly connected to the upper surface of the turntable. A detection chip is inserted into the inner wall of each positioning frame; a plurality of induction blocks are fixedly connected to the outer wall of the turntable.

The two support plates are symmetrically arranged with respect to the frame. The rotating motor is used to drive the rotating rod to rotate.

[0011] When this technical solution is in use, the rotating motor drives the rotating rod to rotate. The turntable drives a plurality of positioning frames to rotate, and the detection chip moves out from between the photosensitive sensor and the detection light source. At the same time, the turntable drives another positioning frame to rotate, and the other positioning frame drives the detection chip to rotate into the gap between the detection light source and the photosensitive sensor, and the other induction block rotates to the position of the positioning distance sensor.

[0012] The technical effects and advantages of the present invention:

[0013] 1. The present invention adopts an inclination transformation detection component. The controller starts the electric cylinder, which drives the socket slider to move rightward. The socket slider slides rightward along the inner wall of the support frame. The socket slider drives the displacement frame to move rightward, and the displacement frame drives the guiding slide rod to incline downward. The inclined sleeve block inclines downward along the inner wall of the inclined frame. The inclined sleeve block drives the connecting frame to incline downward, and the connecting frame drives the support frame to incline downward. The linkage screw drives the two threaded sleeve blocks to incline downward, and the threaded sleeve blocks drive the sleeve frame strip to incline downward, facilitating the detection of the absorbance at different points of the detection chip, enabling inclined multi-point detection, not only making the detection more comprehensive but also greatly improving the detection efficiency.

[0014] 2. Through the displacement detection component of the present invention, when the adjustment motor starts, the linkage screw rotates. The linkage screw drives the two threaded sleeve blocks to approach each other under the action of the screw transmission force. One threaded sleeve block moves rightward along the inner wall of the support frame, and the other threaded sleeve block moves leftward along the inner wall of the support frame. The detection light source is located at the left side of the detection chip, and at the same time, the photosensitive sensor is located at the right side of the detection chip. The detection light source and the photosensitive sensor can locate the detection position of the detection chip and adjust to the specified position for detection, making the detection more comprehensive.

[0015] 3. The present invention adopts a switching detection component. The rotation motor drives the rotating rod to rotate, and the rotating rod drives the turntable to rotate. The positioning frame drives the detection chip to rotate. The detection chip moves out from between the photosensitive sensor and the detection light source. The turntable drives another positioning frame to rotate, and the other positioning frame drives the detection chip to rotate into the gap between the detection light source and the photosensitive sensor. When the positioning distance sensor senses the distance to another induction block, the controller closes the adjustment motor, quickly realizing switching detection for multiple detection chips and greatly improving the detection efficiency.

[0016] Due to the mutual influence of the above multiple functions, first, the detection light source is located at the left side of the detection chip, and at the same time, the photosensitive sensor is located at the right side of the detection chip. Then, the absorbance at different points of the detection chip is detected by moving. Finally, the turntable drives another positioning frame to rotate, and the other positioning frame drives the detection chip to rotate into the gap between the detection light source and the photosensitive sensor. In summary, it is convenient to detect the absorbance at different points of the detection chip, enabling inclined multi-point detection, not only making the detection more comprehensive but also greatly improving the detection efficiency.
