Abstract:
1. In combination, a first substrate comprising a plurality of first chips spaced one from another by first scribe lines, wherein each of said first chips has a semiconductor micro device, a bonding pad ring surrounding the semiconductor micro device, a plurality of bonding pads disposed outside the bonding pad ring and electrically connected to the semiconductor micro device for electrically connecting the semiconductor micro device to an external circuit; a second substrate comprising a plurality of second chips spaced one from another by second scribe lines, wherein each of said second chips has a bonding pad ring corresponding to the bonding pad ring of the first chips; and a plurality of bump rings each bump ring respectively being disposed between the bonding pad ring of one of the first chips and the bonding pad ring of one of the second chips for bonding the first and the second chips, so as to form a hermetical cavity; wherein each second scribe line is substantially aligned with the bonding pads of one of the first chips; and wherein the first and second scribe lines are configured for the first substrate and the second substrate to be cut respectively so as to form a plurality of individual packages.
