[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Reference Figs. 1-3 A biomimetic friction-enhancing structure with high tangential friction includes a top contact block 1, a middle support block 2 fixedly connected to the bottom of the top contact block 1, and an end support block 3 fixedly connected to the side of the middle support block 2 away from the top contact block 1. The top contact block 1 is conical, the middle support block 2 is cylindrical, and the end support block 3 is disc-shaped. The top contact block 1, the middle support block 2, and the end support block 3 are integrally formed. The biomimetic friction-enhancing structure has a lifespan of up to one year, and the number of cycles depends on the specific application scenario. The working temperature is consistently between -40 degrees Celsius and 260 degrees Celsius, and the working pressure is at atmospheric pressure or in a vacuum environment. It is mainly used for handling semiconductor wafers at high temperatures, providing high tangential friction and low normal adhesion, thereby improving the speed, efficiency, and stability of wafer handling. The top contact block 1, the middle support block 2, and the end support block 3 are all made of polymer materials, including silicone rubber.

[0031] Reference Figs. 2-3 The top contact block 1 has a maximum diameter of 8 mm, the middle support block 2 has a diameter of 4 mm, and the distance between the end of the top contact block 1 furthest from the middle support block 2 and the end of the end support block 3 furthest from the middle support block 2 is 3.7 mm. The middle support block 2 has a diameter of 4 mm, and the end support block 3 has a diameter of 6 mm. The maximum diameter of the top contact block 1 (8 mm) ensures a moderate contact area with the wafer surface, providing sufficient friction while avoiding excessive pressure concentration on the wafer. The 4 mm diameter of the middle support block 2 ensures uniform force transmission and guarantees the stability and deformation resistance of the structure at high temperatures. The 6 mm diameter of the end support block 3 provides sufficient contact area with the handling device, effectively distributing the load and enhancing support stability. The 3.7 mm distance between the top contact block 1 and the end support block 3 ensures that the entire structure maintains a balance between rigidity and flexibility during use, providing good support while adapting to deformation requirements in high-temperature environments.

[0032] Working Principle: The biomimetic friction-enhancing structure consists of a top contact block 1, a middle support block 2, and an end support block 3, employing an integrated molding design and made entirely of high-temperature resistant silicone rubber. During wafer handling, the conical design of the top contact block 1 forms point contact with the wafer, concentrating pressure to increase friction, preventing wafer slippage, and avoiding surface damage. The middle support block 2 is cylindrical, responsible for evenly transferring the force from the top to the end support block 3, and absorbing stress changes caused by high temperatures through elastic deformation. The end support block 3 is disc-shaped, making close contact with the handling device, increasing the support area to improve overall stability.

[0033] Through geometric design and material properties, the structure maintains shape stability at high temperatures. The microscopic deformation of the top contact block increases friction, and the middle and end support blocks work together to ensure the accuracy and safety of the wafer during handling.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
