Description

Technical Field

[0001] This utility model relates to the field of wafer processing, specifically to a fully automatic iron ring expanding machine. Background Technology

[0002] Wafer fabrication is a core step in semiconductor manufacturing, involving the entire process of precision manufacturing from high-purity silicon raw materials to integrated circuit chips. This process uses multiple physical and chemical steps to transform silicon wafers, which are several inches in diameter, into wafers with nanoscale circuits, and finally cut them into individual chips for use in electronic devices.

[0003] In the wafer fabrication process, automated film expanders are key equipment used in the chip separation process after wafer dicing. Their core function is to precisely control the film expansion process, separating chips that are tightly adhered to the wafer surface at uniform intervals, facilitating subsequent chip pick-up and packaging processes. The working principle of this equipment is based on a combination of mechanical motion and film material properties. It typically uses a servo motor or cylinder to drive the vertical movement of the working disc, while an expanding ring or locking mechanism applies radial pressure to the protective film, causing the film surface to be stretched uniformly under specific tension. During this process, the elastic deformation of the film and the stress release from the wafer dicing ridges work together to automatically separate the originally tightly packed chips while maintaining the chip's positional accuracy on the film surface.

[0004] For example, patent application CN202510422268.2, entitled "An Invention Patent for a Wafer Expanding Device," includes an outer ring assembly of the expanding stage, an inner ring assembly of the expanding stage, a reciprocating pressing assembly of the expanding stage, and a wafer expanding lifting actuator. The wafer expanding lifting actuator drives the outer ring assembly of the expanding stage in the upper center to move vertically. The inner ring assembly of the expanding stage is installed in the inner ring of the outer ring assembly, realizing fully automatic expanding. However, its structure is simple, and its expanding efficiency is poor. Utility Model Content

[0058] The large iron ring holding mechanism 2 and the small iron ring holding mechanism 3 are located on both sides of the workbench 1, dividing the workbench 1 into the movement area of ​​the large iron ring 16 and the movement area of ​​the small iron ring 17, avoiding interference between the two in their strokes and ensuring the accuracy of their movement paths; the first picking and unloading mechanism 4 and the second picking and unloading mechanism 5 respectively pick up the large iron ring 16 and the small iron ring 17, so that the first transfer mechanism 6 and the second transfer mechanism 7 can transfer the large iron ring 16 and the small iron ring 17; the large iron ring 16 and the small iron ring 17 undergo the film expansion process in the film expansion mechanism 12. The film expansion mechanism 12 is set at both ends of the film expansion slide rail 10, making full use of the installation space of the workbench 1, improving the utilization rate, and realizing uninterrupted film expansion, thereby improving the film expansion efficiency.

[0059] Please refer to Figure 5 , 6 8 and Figure 9As shown, specifically, the film expansion mechanism 12 includes an upper frame 121 and a lower frame 122 that are relatively fixed on the worktable 1. The upper frame 121 is provided with a large iron ring pressing assembly 123 and a small iron ring pressing assembly 124, and the pressing part of the large iron ring pressing assembly 123 corresponds to the large iron ring 16 on the film expansion stage 11.

The baffle 22 is located on one side of the opening of the holding frame 211, and an inlet / outlet channel 221 is formed on the baffle 22, which communicates with the opening. The lifting assembly 21 drives the holding rack 211 to rise, making the large iron rings 16 and small iron rings 17 of the first layer inside the holding rack 211 level with the inlet / outlet channel 221, thus completing the preparation for feeding and discharging the large iron rings 16 and small iron rings 17 inside the holding rack 211. The first picking and discharging mechanism 4 and the second picking and discharging mechanism 5 both pass through the inlet / outlet channel 221 to pick up and place the large iron rings 16 and small iron rings 17. After completing one picking and discharging operation, the lifting assembly 21 drives the holding rack 211 to rise, making the large iron rings 16 and small iron rings 17 of the next layer level with the inlet / outlet channel 221.

Furthermore, a positioning cylinder 426 is fixed on the positioning frame 424. A limit block 427 is fixed to the driving end of the positioning cylinder 426. The positioning cylinder 426 drives the limit block 427 to abut against the sides of the large iron ring 16 and the small iron ring 17, thereby limiting the position of the large iron ring 16 and the small iron ring 17 and preventing them from shifting position during travel. During the material handling process, the pick-and-place platform 421 moves to one side of the inlet / outlet channel 221 of the baffle 22 via the pick-and-place slide rail 41. The guide slide rail 423 is parallel to the extension direction of the inlet / outlet channel 221, and the pick-and-place gripper 422 is located in the extension direction of the inlet / outlet channel 221.
