Capillary effect based tsv filling method
WebAbstract: Via-filling is a critical and costly process of TSV fabrication and is usually realized by Cu-plating, CVD, etc. Liquid metal via-filling made by pressing solder from a melting solder pool into via holes faces problems of wafer breakage caused by pressure differential and cutting off solder-vias from the pool. A liquid bridge pinch-off effect based cutting-off … WebCapillary underfill materials applied after chip placement are designed with optimized rheology for deposition consistency and uniform flow. Henkel’s capillary underfills for flip-chip applications are formulated with small fillers to enable good jetting performance, fast flow, and thorough bump protection.
