, most reliable semiconductor package platforms on the market today.  Applications for wafer-level CSP include power management, transceivers, sensors, wireless charging, codecs, and specialty silicon for new or unique functionality.

•WLFO packages (also known as low-density fan-out packages) are utilized for ICs where the die surface area is too small to accommodate all of the required bond pads.  The fan-out package enlarges the bondable surface area by building a border around the die using low-cost molding compound.  These packages can include multiple die.  Applications for WLFO packages include power management, transceivers, radar and specialty silicon.

•SiPh and CPO allow for the integration of fiberoptic interconnects both within a package and within the server architecture to reduce power consumption, heat generation and improve performance.  Amkor has supported previous generations of SiPh packaging needs and is aligned with the market to support its future needs, through chip on wafer, chip on chip and other advanced packaging solutions.  

•SWIFT, also known as high-density fan-out, can either replace the laminate substrate with a thinner structure or reduce the complexity of the substrate by housing the dense interconnects in the SWIFT structure, allowing for a less expensive substrate that provides a high level of performance with a balanced cost structure.  SWIFT solutions enable high performance in a compact form factor that combines tiled processors, memory, I/O (input/output) die and other peripheral ICs.

Mainstream Products

Our Mainstream Products use wirebond interconnect technology to connect a die to a leadframe or substrate package carrier and include leadframe packages, substrate-based wirebond packages and micro-electro-mechanical systems (“MEMS”) packages.

Leadframe Packages:  Leadframe packages use wirebond or flip chip technology to connect a die to a leadframe package carrier.  Leadframe packages are used in many electronic devices and remain the most practical and cost-effective solution for many low to medium pin count analog and mixed signal applications.

Traditional leadframe packages support a wide variety of device types and applications.  Two of our most popular traditional leadframe package types are small outline IC and quad flat package, commonly known as “dual” and “quad” products, respectively, based upon the number of sides from which the leads extend.  The traditional leadframe package family has evolved from “through hole design,” where the leads are plugged into holes on the circuit board to “surface mount design,” where the leads are soldered to the surface of
