Devices are provided for the controlled release of drug or other molecules. The devices include (1) a substrate, which optionally includes two or more substrate portions bonded together, (2) at least two reservoirs in the substrate, (3) a release system disposed in the reservoirs that includes the molecules for release and optionally a matrix material, and (4) active or passive means for controlling release of the molecules from the reservoirs. In one embodiment, a reservoir cap is positioned on, or within a portion of, the reservoir and over the molecules, so that the molecules are controllably released from the device by diffusion through or upon disintegration of the reservoir cap.
