Abstract:
1. A method of forming a drug delivery device, comprising: laser forming a top ceramic plate to include an inner portion including a plurality of top laser micromachined through-holes while not lasering a planar outer portion; forming a plurality of top nanochannels into said top ceramic plate to provide fluid connections between neighboring ones of said plurality of top laser micromachined through-holes; laser forming a bottom ceramic plate to include an inner portion including a plurality of bottom laser micromachined through-holes while not lasering a planar outer portion; forming a plurality of bottom nanochannels into said bottom ceramic plate to provide fluid connections between neighboring ones of said plurality of bottom laser micromachined through-holes; applying a bonding material to at least a portion of said planar outer portion of said top ceramic plate and/or said planar outer portion of said bottom ceramic plate; aligning said top ceramic plate and said bottom ceramic plate so that said plurality of top laser micromachined through-holes and said plurality of bottom laser micromachined through-holes are laterally offset from one another; and bonding said top ceramic plate to said bottom ceramic plate with said bonding material.
