Temporary Wafer Bonding Processing Theory | Brewer Science

The temporary bonding process consists of reversibly mounting a device wafer to a carrier wafer with a polymeric bonding material system. The bonding materials and the carrier wafer mechanically support the device wafer during thinning (back-grinding) and subsequent backside processing that includes processes such as deposition, dry and wet etching, plating, and cleaning, among others.
