Patent ID: 8715592

Claim:
An assembly comprising an integrated electronic-microfluidic device at is mounted on a circuit board, the integrated electronic-microfluidic device comprising: a semiconductor substrate on a first support; an electronic circuit on a first semiconductor-substrate side of the semiconductor substrate; a signal interface structure to an external device, the signal interface structure being arranged on the first semiconductor-substrate side and configured to receive electrical signals from the electronic circuit; a microfluidic structure formed in the semiconductor substrate, the microfluidic structure being configured to confine a flow of a fluid including to and from the microfluidic structure to only a second semiconductor-substrate side that is opposite to the first semiconductor-substrate side and faces away from the first support; a second support on the second semiconductor-substrate side, the second support having an opening that allows a flow of the fluid to and from the microfluidic structure; wherein the external-contact elements of the integrated electronic-microfluidic device are connected to contact structures on the circuit board.
