[0002] In the field of chip manufacturing and processing, with the continuous development of technology, the application of chips is becoming more and more widespread, from electronic devices to industrial automation and various aspects cannot be separated from chips. In the process of manufacturing and testing of chips, the fixation and clamping of chips are very important links, which are directly related to the processing precision and quality of chips. A good chip fixing method can ensure that the chip remains stable during processing and testing, avoiding processing errors or inaccurate testing caused by shaking or displacement, which is of great significance to improve the production efficiency and performance of chips.

[0003] In the related art, in the past chip fixing operation, for the chip with length and width greater than 1mm, two conventional methods are usually used for fixation. One is vacuum adsorption method, which adsorbs and fixes the chip at a specific position by generating vacuum suction force; the other is sliding clamp method, which clamps the chip by sliding the clamp. These two methods can meet the basic fixing requirements when processing large-sized chips, and provide certain stability guarantee for the processing and testing of chips.

[0004] For the related art in the above, when the length or width of the chip is less than 1mm, the existing fixing method has obvious defects. The vacuum adsorption method cannot provide enough fixing force, and it is difficult to stably fix the small-sized chip. The sliding clamp method not only easily clamps the chip, but also causes chip damage or loss; therefore, it is urgent to provide a structure for improving the stability of micro chip clamping.
