Several different D2W bonding methods are available and selected depending upon the application and customer requirements. In direct placement D2W (DP-D2W) bonding, the singulated dies are bonded to the target wafer one by one using a pick-and-place flip-chip bonder. Plasma activation and cleaning of the surfaces of the dies on the handler wafer are essential steps for establishing a high-yielding bond and electrical interface between the dies and target wafer. This is where the EVG320 D2W activation system comes in.
