Abstract:
A vacuum fusion bonding apparatus for producing embedded microstructures, including:an oven platform having a flat upper surface for supporting associated substrates having microstructures therein to be fusion bonded,a vacuum facility including a pumpout block having a flat surface and a vacuum manifold therein adapted to be mounted on a surface of one of such associated substrates to be fusion bonded and adapted to be in alignment with at least one opening in one of such associated substrates to be fusion bonded,a blank-off block having a flat surface adapted to be mounted on the surface of said one of such associated substrates to be bonded and adapted to be positioned over an opening in the one of such associated substrates to be fusion bonded, and in spaced relation to said pumpout block, andremovable clamping means adapted to contact such associated substrates to be bonded and for temporarily retaining together and aligning such associated substrates to be bonded are located intermediate said platform and said blocks.
