Abstract:
A method for hermetically sealing reservoirs of a microchip device, the method comprising:providing a primary substrate having a front side and a back side, the substrate comprising a plurality of reservoirs positioned between the front side and the back side, each reservoir being loaded with molecules or a secondary device for controlled release or exposure, the reservoirs having at least one opening in need of sealing, the primary substrate including one or more hermetic sealing materials; providing a hermetic sealing substrate having a surface composed of one or more hermetic sealing materials; positioning the hermetic sealing substrate over the reservoir openings and contacting said hermetic sealing materials of the primary substrate with said hermetic sealing materials of the hermetic sealing substrate; and applying energy to the contacted sealing materials effective to form a hermetic seal between the hermetic sealing substrate and the primary substrate to hermetically seal each of the reservoir openings.
