High frequency characteristics of low temperature processing and high density integrated capacitor on organic substrates

Rapidly growing performance and mixed-signal integration is driving the need for product and component miniaturization in electronics applications. Integral passive technology is a potentially attractive solution to replace discrete passives. Capacitors are widely used for broad ranging applications including filtering, tuning and power decoupling. This paper presents the performance characterization of two low temperature processes that are compatible with organic substrates. RF characterization up to 10 GHz was performed to extract the impedance profile, effective capacitance and capacitance density parameters.
