Abstract:
A method for forming an electro-fluidic connection from a microfluidic substrate to a die having at least one active electrical element thereon, comprising:forming at least one bond pad on the die that is electrically connected to the at least one active electrical element, forming a seal ring on the die on the outside of the at least one bond pad and the at least one active electrical element, forming at least one matching bond pad on the microfluidic substrate for connection to external support electronics, forming a matching seal ring on the microfluidic substrate on the outside of at least one fluidic via hole, bonding the at least one bond pad to the at least one matching bond pad with a conductive sealant to form electrical connection from the microfluidic substrate to the active electrical element, and bonding the seal ring to the matching seal ring with a sealant to form a fluidic seal around the active electrical element.
