Abstract
Silicon conductive vias and pedestals are disclosed for use in microwave integrated circuits. The pedestals are isolated from a ground plane on the bottom surface by glass, while the vias are used to make electrical contact to ground. Electrical circuit elements in the top surface of the integrated circuit are selectively grounded or isolated by the choice of connection to a via or pedestal, respectively.
