Abstract
A microfluidic device or system and method of manufacture is disclosed wherein a the microfluidic device or system is made from individually processed and patterned layers of LTCC green tape, that is aligned and stacked, and then co-fired to form a LTCC ceramic modules. Subsequently, microfluidic device die and/or integrated circuit device die are bonded to pre-determined areas of the modules and micro-mechanical and/or micro-electro-mechanical devices and/or systems are fabricated into or onto the surfaces of the modules. The modules are aligned bonded together to form the microfluidic devices and systems. The use of LTCC materials and techniques provides a low-cost flexible and easily customizable approach for microfluidic devices and systems that can be designed and transitioned into production with significant development time and cost.
