ABSTRACT:
Integrated circuits are formed by bonding two substrates together on a moat or recess. If the moat is exposed at a side wall, an optical fiber is inserted therein and communicates optically with a photoelectric device in the substrate by a slant side wall of the moat. If the moat is sealed by a cover layer resulting from removing all or most of the top substrate leaving the bonding layer as a cover, a pressure responsive device is formed on the cover layer directly or in the remaining top substrate over the sealed cavity.
