Multi-level integrated circuit for wide-gap substrate bonding

摘要

An integrated circuit (30) includes a substrate (10) having an etched surface and a non-etched surface. The etched surface contains circuit elements (22, 24) and the non-etched surface contains a bonding surface (18). The non-etched surface is located at a predetermined height (12) from the etched surface. Bonding this integrated circuit (30) with another substrate creates a wide-gap between the substrates that is preferably evacuated and hermetically sealed.
