Abstract:
A method of making an inorganic semiconductor structure suitable for micro-transfer printing includes providing a growth substrate and forming one or more semiconductor layers on the growth substrate. A patterned release layer is formed on the conductor layer(s) and bonded to a handle substrate. The growth substrate is removed and the semiconductor layer(s) patterned to form a semiconductor mesa. A dielectric layer is formed and then patterned to expose first and second contacts and an entry portion of the release layer. A conductor layer is formed on the dielectric layer, the first contact, and the second contact and patterned to form a first conductor in electrical contact with the first contact and a second conductor in electrical contact with the second contact but electrically separate from the first conductor. At least a portion of the release layer is removed.
