Abstract:
1. A method for hermetically sealing a device inside a micro- or nano- package, comprising the steps of: sealing a package base and cap with a metallic sealing gasket, wherein said metallic sealing gasket is between said package base and said package cap, wherein said sealing is accomplished with a compressive force sufficient to effect a permanent hermetic cold-weld seal without the addition of heat; wherein said sealing is accomplished within a sealing chamber having a sealing chamber environment, and wherein at least a portion of said sealing chamber environment is captured within said micro- or nano- package; and wherein said metallic sealing gasket is comprised of metallic nanoparticles with an average diameter below 200 nanometers, wherein said permanent hermetic cold-weld seal is accomplished without the need for additional holding force structures or sealants.
