Description

Multi-step jacking structure with adjustable jacking height Technical Field The utility model relates to the technical field of chip manufacturing, in particular to a multi-step jacking structure with an adjustable jacking height. Background In the field of semiconductor chip manufacturing, chip stacking technology is becoming more and more widely used as an effective means for improving chip performance and reducing chip size. In the chip stacking process, chip release is one of the key processes, and the core is to separate the chip from its carrier (e.g. DAF, die Attach Film, chip adhesive film) safely and efficiently. In order to achieve the aim, various jacking devices are generated, wherein the multi-step jacking is specially designed for chip demolding equipment, and the multi-step jacking has obvious application value in specific scenes by virtue of the unique working principle and structural design. The multi-step roof is typically constructed of a metal shell enclosing an internal vacuum unit, the core mechanical structure of which comprises three rectangular modules (blocks) that can be synchronously controlled by a single motor. In the jacking operation, the three modules are sequentially jacked in three steps, and gradual separation of the chip and the DAF is realized through progressive acting force. The design can obviously increase the contact area of the grabbing head and the chip after the chip is taken off, effectively disperses the stress generated in the jacking process, thereby reducing the damage risk of the chip, and is particularly suitable for chip stacking products sensitive to mechanical stress. Although the existing multi-step jacking has advantages in specific application scenes, the structural design of the existing device has obvious limitation that the three-step jacking height of the existing device is a fixed value and cannot be dynamically adjusted according to the requirements of the chip stacking processes with different thicknesses.
