Method of using integrated electro-microfluidic probe card

A method comprising:

• mounting an integrated electro-microfluidic probe card to a device area on a bio-sensor device wafer, wherein the electro-microfluidic probe card has a first major surface and a second major surface opposite the first major surface;
• electrically connecting an electronic probe tip extending from the first major surface of the integrated electro-microfluidic probe card to a conductive area of the device area;
• printing a test fluid onto the device area;
• and
• measuring via the electronic probe tip a first electrical property of one or more bio-FETs of the device area based on the test fluid.

A method comprising:

• mounting an integrated electro-microfluidic probe card to a device area on a bio-sensor device wafer, wherein the electro-microfluidic probe card has a first major surface and a second major surface opposite the first major surface;
• electrically connecting at least one electronic probe tip extending from the first major surface to a corresponding conductive area of the device area;
• placing a first test fluid on the device area, wherein the placing of the test fluid comprises stamping or printing;
• and
• measuring via the at least one electronic probe tip a first electrical property of one or more bio-FETs of the device area based on the first test fluid.
