The solution for high density, complex stack combination for innovative form factors

The FlipStack® CSP family utilizes Amkor’s industry-leading ChipArray® BGA (CABGA) manufacturing capabilities, in combination with Amkor’s flip chip CSP (fcCSP) technology. This broad high-volume infrastructure enables the rapid deployment of advances in die stacking technology across multiple products and factories to achieve the lowest total cost. FlipStack CSP technology enables the stacking of a wide range of different semiconductor devices to deliver the high level of silicon integration and area efficiency required in portable multimedia products. Many customers have relied on Amkor to solve their highest density and most complex device stack combinations.

FlipStack CSP technology enables smaller, lighter and more innovative new product form factors at a lower cost. This solution addresses a range of design requirements, and enables a wide variety of applications, including: portable devices (tablets, smartphones and digital cameras). Additional applications include gaming, automotivecomputing and industrial.
