Abstract

Described herein are structures and techniques for providing an LC cell having a hermetically sealed cover disposed over a fill hole provided in a superstrate. The superstrate and cover have adhesion layers disposed thereon. Solder is disposed or otherwise provided around the fill hole (e.g. either on the cover or the superstrate or as a separate piece). The cover is then disposed over the fill hole and the solder is reflowed to form the hermetic seal over the fill hole.
