A solution space design methodology is presented for optimization of off-chip inductors. The analysis has been performed for an advanced wafer level redistribution manufacturing process. Electromagnetic simulations were performed to extract the characteristics of different inductor designs. It was observed that the design optimization should be tuned to the operating frequency.

High Flexibility

AbstractHolograms have found their use as optical elements in a variety of applications. Yet using them with incoherent and divergent lightsources like LEDs proves difficult, as their characteristics need to be simulated by lasers during manufacturing to get a correct reconstruction of the desired light distribution. We present a new setup to allow for a high flexibility during the manufacturing process, which is able to produce volume holographic cell arrays (VCAs) that can be illuminated directly with uncollimated LEDs. Results are presented for the case of reflection holograms.

The Cost

Abstract Fan-out wafer-level packaging (FOWLP) and embedded die packaging offer similar advantages over traditional packaging technologies. For example, both packages can be quite thin since the die is placed early in the manufacturing process and the package is fabricated around the die. This is in contrast to traditional packaging technologies, in which the package is fabricated first, and then the die is placed on top of the package. This results in a thicker package compared to fabricating the package around the die. Due to the ongoing miniaturization market requirements, thinner packages are becoming increasingly important. Both FOWLP and embedded die packaging also provide the capability of placing multiple die and passives in a single package. This capability can have both size and performance benefits since the interconnect distance between the embedded components is shorter. In this paper, the cost and cost drivers of FOWLP and embedded die packaging technologies will be compared. Activity based modeling will be used to characterize the cost of each activity in the two manufacturing flows.
