Radio frequency tuning using a multichip module electrical interconnect structure
Abstract
A method for tuning a resonant frequency of wireless communication circuitry on a multichip module including a plurality of chips includes applying an electrical insulator to an upper surface of the multichip module; creating a plurality of openings in the electrical insulator, each opening being positioned at a successive one of the bond pads to be electrically connected to create a plurality of exposed bond pads; applying metal to each exposed bond pad to form a successive one of a plurality of interconnect bases; removing a portion of the layer of photoresist to create a plurality of bridge supports, each bridge support positioned between a successive pair of interconnect bases; applying metal to each bridge support and associated interconnect bases to form a successive one of the interconnect traces; removing the bridge supports; and disconnecting one or more of the interconnect traces as necessary to obtain a target resonant frequency.
