Abstract :
Bond Via Array (BVA™) technology has been developed to enable more than 1000 vertical connections between memory and processor components in a standard outline Package-on-Package (PoP) configuration. This higher density interconnect more than doubles current PoP capability and thereby addresses next generation wide IO mobile device demands for increased bandwidth [1]-[3]. In this paper, we discuss BVA manufacturing process details and associated demonstration test vehicle design. This prototype BVA PoP demonstrates 1020 vertical interconnects at 0.24mm pitch within an industry standard 14 ×14mm package footprint. Information regarding test vehicle design optimization, critical assembly process steps, package reliability, and testing will be discussed along with the overall high volume manufacturing (HVM) readiness of BVA.
