| Abstract: | A method for forming a monolithic seal frame and lid for use with a
substrate and electronic circuitry comprises the steps of forming a
mandrel from a ceramic and glass based material, forming a seal frame and
lid block from a ceramic and glass based material, creating a seal frame
and lid by forming a compartment and a plurality of sidewalls in the seal
frame and lid block, placing the seal frame and lid on the mandrel such
that the mandrel fits within the compartment, and cofiring the seal frame
and lid block. |
