Microchip assembly with electrical element in sealed cavity
First Claim
1. A microchip assembly comprising:
- a first substrate assembly having a generally planar exterior surface portion and having a cavity therein with an opening encompassed by said planar exterior surface portion;
a second substrate assembly having a generally planar exterior surface portion positioned in opposite parallel relationship with said exterior surface portion of said first substrate assembly;
a patterned conductive film layer sandwiched between said exterior surface portions of said first and second substrate assemblies comprising;
a sealing ring portion positioned in continuous circumscribing relationship with said cavity opening and continuous engaging relationship with said exterior surface portions of said first and second substrate assemblies and sealingly bonded thereto;
an electrical circuit element portion, having at least a part thereof encompassed by said sealing ring portion, bonded to said exterior surface portion of said second substrate assembly.

Abstract
A method of producing a microchip having at least a portion of an electrical circuit element contained within a hermetically sealed enclosure comprising the steps of: forming a cavity in a first substrate assembly which has a cavity opening at a first surface portion of the first substrate assembly; forming an electrical circuit element and sealing ring from a film applied to a first surface portion of a second substrate assembly with the sealing ring arranged in circumscribing relationship with at least a portion of the circuit element; positioning the first surface portion of the first substrate assembly opposite the first surface portion of the second substrate assembly with the sealing ring located in circumscribing relationship with the cavity opening; sealingly bonding the sealing ring to the first surface portion of the first substrate assembly.
