Interposer with signal and power supply through vias

摘要

A planar thin film multi-layer capacitor having a high dielectric constant with a plurality of conductive through vias and a plurality of pairs of conductive through vias having a low dielectric constant and operating in a transverse electromagnetic wave mode for high frequency signals on the pairs of vias. Vias coupled to the capacitor are arranged to propagate alternate polarity. The interposer is adapted for coupling directly to a die.
