|Achieving Ceramic-like RF Capacitors Requirements with Organic Based Materials|
|Keywords: capacitance, embedded, RF|
|Embedded capacitors have been widely explored, especially for digital functions such as decoupling. To date, however, it has been more difficult to use embedded capacitors as part of RF circuits such as filters. There are several reasons, besides the circuit design issue, which cause this and they are primarily due to the fact that most materials used for forming embedded discrete capacitors have relatively high loss and low dielectric constant (at GHz frequencies). Also, the capacitance can easily change as a function of temperature, influencing the total system performance. New and novel organic-based composite materials have been developed to address the important material issues described. In the present study, modified epoxy based resins with ceramic fillers (dispersed into the resin) are used which allows electrical properties to be stable in the frequency range up to 10GHz. It can be incorporated into organic chip package and, unlike ceramic-based LTCC (which need an expensive sequential multi-layer fabrication process) they can utilize large area processing that is typical, and available in high volume manufacturing. This material is formulated for RF module designers to successfully implement embedded RF capacitors into their organic chip package designs and thus improve form factor, electrical performance and possibly reduce overall costs.|
