Abstract
Embodiments of methods for sealing a glass microstructure assembly comprise providing one or more side retainer members on a base plate adjacent the glass microstructure assembly, the side retainer members having a height less than an uncompressed height defined by the glass microstructure assembly. The methods also comprise compressing the glass microstructure assembly via a load bearing top plate in intimate contact with the top glass layer while heating the glass microstructure assembly and the top plate to a glass sealing temperature, the glass sealing temperature being a temperature sufficient to make glass viscous, wherein the glass microstructure assembly is compressed until the load bearing top plate contacts the side retainer members, and wherein the lower surface of the top plate maintains adhesion to the upper surface of the top glass layer at the glass sealing temperature while the load bearing plate is supported by the side retainer members.
