Abstract: Reliable plasma dicing of a wafer with a die attach film (DAF) to the bottom wafer surface to singulate it into individual dies is disclosed. Laser processing is employed to form mask openings in a passivation stack of a processed wafer to serve as a dicing mask. A combination of plama dicing and laser cutting is employed. Plasma is employed to etch the wafer while laser is employed to cut the DAF.

Abstract: Lamination systems and methods of fabricating devices are disclosed. The lamination system includes multiple processing modules for delaminating a backgrinding (BG) from a surface of the wafer and laminating a dicing tape on the surface of the wafer. The system includes a wafer receiving module which is configured to hold the wafer in place with a position chuck throughout the delamination and lamination process. By using a single positioning chuck, more efficient processing is achieved. For example, there is no need to re-lign the wafer when it is moved from one chuck to another.
