Abstract
A cross-fill metal fill pattern technique is provided such that portions of a metal fill pattern are patterned to accomplish a secondary function. For instance, in the exemplary embodiments, ever other trace or line of interdigitated fingers is routed to a ground, while the interceding traces or lines of interdigitated fingers are routed to a power supply. In this way, a capacitor function is formed across the power supply, providing additional decoupling for the power supply. Moreover, a suitably tight cross-fill metal fill pattern (i.e., higher density of metal) provides an electrical shielding function for electromagnetic radiation passing therethrough.
