Abstract
A microfluidic device includes first and second glass substrates bonded together. The first glass substrate has first and second opposed surfaces. A die pocket is formed in the first opposed surface, and a through slot extends from the die pocket to the second opposed surface. The second glass substrate is bonded to the second opposed surface of the first glass substrate whereby an outlet of a channel formed in the second glass substrate substantially aligns with the through slot. The channel of the second glass substrate has an inlet that is larger than the outlet.
