Polyimide wafer bonding
WebTemporary bonding of wafers to a glass carrier has emerged as a viable method for back thinning and subsequent backside processing. The processed thin wafers are finally debonded from their carriers prior to stacking. Excimer laser debonding enables the use of polyimide-based temporary adhesives WebMay 29, 2012 · Temporary wafer bonding for thin wafer processing is one of the key technologies of 3D system integration. In this context we introduce the polyimide material HD3007 which is suitable for temporary bonding of silicon wafers to carrier wafers by using a thermo compression process. Coating and bonding processes for 200 mm and 150 mm …
