    Abstract:

    As a key technology to solve advanced manufacturing and packaging, temporary bonding technology, as a high reliability solution for the processing of thin wafer devices, has attracted more and more attention. According to the different ways of de-bonding, thermal slip de-bonding material system and ultraviolet laser de-bonding material system are introduced in this paper. Thermal slip de-bonding materials (WLP TB130 and WLP TB140) were manufactured. Both of materials showed higher heat resistance and chemical resistance properties than foreign products. And the 5% weightlessness of materials were over 400 ℃. WLP TB140 even could be separated from the supporting waferat 160 ℃ by thermal-slipde-bonding technique. Ultraviolet laser de-bonding material system with release layer (WLP LB210) and adhesive layer (WLP TB4130) was manufactured, ultra-thin device bonded were separated from the supporting wafer using ultraviolet laser at room temperature and stress free.
