Patent ID: 8080872

Claim:
A package for use in encapsulating an electronic device, comprising: a dielectric frame having first and second sides, an aperture, a raised shelf portion defined along an internal perimeter of said dielectric frame and extending outwardly from said second side, said raised shelf portion defining a first thickness of said dielectric frame, and a raised sidewall extending outwardly from said second side along an external perimeter of said dielectric frame, said raised sidewall defining a second thickness of said dielectric frame, said second thickness being greater than said first thickness; a metallic component bonded to said dielectric frame and extending across said aperture; a seam weldable, low-profile metallic seal ring bonded to said raised sidewall of said dielectric frame, and wherein said dielectric frame is alumina and said metallic component is a compacted mixture of powders consisting essentially of molybdenum, tungsten, copper, silver, and alloys thereof.
