Thin Wafers, Temporary Bonding Equipment & Materials Market

The report provides a temporary wafer bonding equipment forecast which shows that 10% of the total thin wafer shipment will experience a temporary bonding step by 2017. So, while temporary bonding equipment is still a small market today, it is expected to grow as the need for thin wafer handling grows. In fact, we estimate the market for temporary bonding tools to be more than $250M by 2017. Currently, shipped bonder/debonders are for Power and 3D ICs applications. However, we believe 3D ICs will become the predominant application for temporary bonders > 2015.

Thin wafer handling will enjoy increased importance in the coming years, but as chips get thinner and wafer diameter increases, thinning/handling procedures are required. This implies development in wafer thinning, wafer dicing and wafer temporary bonding.

Temporary bonding implies know-how in process and chemistry, and an understanding of the final application requirements. Temporary bonding is a complex technology, requiring an interface material (sometimes called the “Magic” material) that is strong enough to withstand post-processing but which can be easily removed afterwards. As the main concern for temporary bonding materials (wax, tape or glue) is temperature stability, the material must be strong enough to withstand processing steps (metallization, etching, grinding). Another issue is the choice of carrier material. Carrier lifetime depends on its capability to withstand steps such as grinding, etc., and carrier lifetime should be at least tens of times, though this is not yet the case today.
