摘要：
A method of forming a drug delivery device includes laser forming a top ceramic plate to include an inner portion including top laser micromachined through-holes while not lasering a planar outer portion. Top nanochannels are formed into the top ceramic plate to provide fluid connections between neighboring to micromachined through-holes. A bottom ceramic plate is laser formed to include an inner portion including bottom laser micromachined through-holes while not lasering a planar outer portion. Bottom nanochannels are formed into the bottom ceramic plate to provide fluid connections between neighboring to micromachined through-holes. A bonding material is applied to the planar outer portion of the top and/or bottom ceramic plate. The top and bottom ceramic plate are aligned so that the top and bottom laser micromachined through-holes are laterally offset from one another. The top ceramic plate is bonded to the bottom ceramic plate with a bonding material.
