Patent ID: 8907227

Claim:
A device having at least a device component positioned on one of a plurality of substrate surfaces comprising: a first substrate having a resistivity of approximately 0.1 ohm-cm to approximately 10 ohm-cm and having at least first and second surfaces; a first electrically-conductive component disposed over the first surface of the first substrate with or without an intermediate electrically-insulating layer; a second electrically-conductive component disposed over the second surface of the first substrate; a cavity formed in the first substrate; a second material having a resistivity higher than resistivity of the first substrate at least partially filling the cavity in the first substrate; and one or more electrically-conductive pathways formed in the second material electrically connecting the first electrically-conductive component and the second electrically-conductive component to form the device; wherein at least one of the first electrically-conductive component and the second electrically-conductive component comprises one or more passive electrical coils embedded within at least one isolation material for resisting changes in electric current; wherein the one or more passive electrical coils are disposed over at least a portion of the second material; and wherein the isolation material is positioned over the first substrate.
