MONOLITHIC LTCC SEAL FRAME AND LID

摘要

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.

主权项

1. A microelectronic circuit package comprising:
a substrate configured to retain one or more electronic circuits, the substrate formed from ceramic and glass material; and a seal frame and lid attached to an upper surface of the substrate, the seal frame and lid comprising:
at least one sidewall with an inner surface and an outer surface, the inner surface defining a compartment, anda lid with a top surface and a bottom surface, wherein the at least one sidewall is monolithically connected to the bottom surface at the perimeter thereof and the at least one sidewall and the lid are each formed from ceramic and glass material.
