The GEMINI® FB automated collective die-to-wafer bonding system features collective D2W (Co-D2W), a potential method for hybrid D2W bonding. As far as Co-D2W bonding is concerned, several dies are shifted to the final wafer in just one process step. The manufacturing flow for the Co-D2W bonding process includes four significant segments: carrier preparation, carrier population, wafer bonding and carrier separation.
The EVG Gemini FB has been designed for D2W bonding and is a decisive element in the Co-D2W integration flow, thereby allowing effective cleaning and shift of carrier mounted dies, bonding and carrier detachment in a single system. The Gemini FB system is industry standard for both wafer-to-wafer and Co-D2W fusion and hybrid bonding.
