Abstract

A microfluidic chip with a high volumetric flow rate is provided that includes at least two vertically stacked microfluidic channel layers, each microfluidic channel layer including an array of spaced apart pillars. Each microfluidic channel layer is interconnected by an inlet/outlet opening that extends through the microfluidic chip. The microfluidic chip is created without wafer to wafer bonding thus circumventing the cost and yield issues associated with microfluidic chips that are created by wafer bonding.
