Abstract

The invention discloses a wafer support device. The device has an annular cylindrical structure so that a semiconductor device area on the front surface of an ultra-thin wafer cannot be blocked. Therefore, a performance test can be performed before encapsulating; problems in a process can be fed back and evaluated timely; and process risks are reduced. The invention also discloses a wafer processing process. In the processing process, the wafer support device is utilized for supporting the ultra-thin wafer in the process of a wafer back surface processing process and the performance test is performed after the wafer back surface processing, so that the problems in the process can be fed back and evaluated timely, and the process risks are reduced.

Description

technical field [0001] The invention relates to the technical field of integrated circuits, in particular to a wafer supporting device and a wafer processing technology. Background technique [0002] With the advancement of integrated circuit technology, semiconductor integrated circuits are developing in the direction of thinner and smaller while the degree of integration, speed and reliability are continuously improved. And with the introduction of through-silicon via (TSV, Through Silicon Via) 3D packaging technology, the requirements for chip thickness are getting higher and higher, and ultra-thin chips have emerged as the times require. The so-called ultra-thin wafer refers to a wafer whose thickness is equal to or less than 100um. At the same time, because ultra-thin wafers have low resistance, low power dissipation and good thermal conductivity, they have also become the focus of research in power electronic devices. [0003] Ultra-thin wafers are usually realized t...
