High-performance inductors for integrated fan-out wafer level packaging (InFO-WLP)

Integrated fan-out wafer-level packaging (InFO-WLP) technology with state-of-the-art quality factor (Q) = 64 in 2.4GHz inductor has been demonstrated for RF systems. For the first time, radio frequency (RF) circuits with InFO-WLP have been fabricated to illustrate how the high Q inductor can be used to dramatically improve performance and power consumption concurrently.
