ABSTRACT:
A structure and method for creating an integrated circuit passivation comprising, a circuit (16) over which an insulating layer (26 and/or 28) is disposed that electrically and hermetically isolates the circuit (16) and a silicon carbide layer (30) to form a passivation (24) to protect a circuit (16), is disclosed.
