Multi-level integrated circuit for wide-gap substrate bonding

摘要

An integrated circuit includes a substrate having an etched surface and a non-etched surface. The etched surface contains circuit elements and the non-etched surface contains a bonding surface. The non-etched surface is located at a predetermined height from the etched surface. Bonding this integrated circuit with another substrate creates a wide-gap between the substrates that is preferably evacuated and hermetically sealed.
