Abstract:
A device interconnect system, comprising:a bonding pad portion disposed on a device substrate and including at a first elevation above the device substrate an electrical conductor constructed and arranged for electrical connection to a bond wire; and a transmission line portion disposed on the device substrate and including an electrical conductor constructed and arranged to electrically couple the electrical conductor of the bonding pad portion to a device at a second elevation above the device substrate different from the first elevation, the electrical conductor of the transmission line portion having a width dimension substantially parallel to the device substrate and a height dimension substantially perpendicular to the device substrate, wherein the width dimension and the height dimension both vary from the bonding pad portion to the device, the height dimension varying from the first elevation to the second elevation in a series of at least two steps, each step being at a respective elevation above the device substrate different from other step elevations and different from each of the first and second elevations.
