Patent ID: 7106598

Claim:
A passive component assembly for a modular electrical circuit, comprising: a plurality of substrates each made of an insulating material, at least one through via formed through each said substrate and filled with a conductive material, a first passive component type being exclusively formed on a first portion of said plurality of substrates of insulating material and at least one component of said first passive component type being in contact with said at least one conductively filled through via of said first portion of said substrates; a second passive component type being exclusively formed on a second portion of said plurality of substrates of insulating material, said second passive component type being different than said first passive component type, at least one component of said second passive component type being in contact with said at least one conductively filled through via of said second portion of said substrates, said first and second portions of said substrates being overlaid in a selected sequence; and a contact pad layer disposed between overlaying substrates for bonding one to another, each said contact pad layer having at least one conductively filled through via for interconnecting at least one component of an underlying substrate with at least one component of an overlying substrate to form an electrical circuit.
