Abstract: A method for forming a cavity in a microfabricated structure, includes the sealing of that cavity with a low temperature solder. The method may include forming a sacrificial layer over a substrate, forming a flexible membrane over the sacrificial layer, forming a release hole through a flexible membrane to the sacrificial layer, introducing an etchant through the release hole to remove the sacrificial layer, and then sealing that release hole with a low temperature solder.
