Abstract
A microchip has a base die with a conductive interconnect and an isolation trench around at least a portion of the conductive interconnect, and a cap die secured to the base die. A seal, formed from a metal material, is positioned between the base die and the cap die to secure them together. The microchip also has a blocking apparatus, between the isolation trench and the metal seal, that at least in part prevents the metal material from contacting the interconnect.
