Abstract:
A compound micro-assembled device comprises a device substrate. A first component having a first native resolution and a second component having a second native resolution different from the first native resolution are both disposed on the device substrate. The device substrate can comprise a device circuit having a native resolution different from or less than the first and second native resolutions. One or more device interconnections electrically connect the first component to the second component or to the device circuit. In certain embodiments, the first component or the second component can be micro-transfer printed onto the device substrate. In certain embodiments, the compound micro-assembled device can be micro-transfer printed onto a destination substrate or the compound micro-assembled device can comprise a destination substrate onto which the device substrate is micro-transfer printed. At least one of the first component and second components and, optionally, the device substrate, comprises at least a portion of a tether.
