Abstract

In certain embodiments, a method of making a semiconductor structure suitable for transfer printing (e.g., micro-transfer printing) includes providing a support substrate and disposing and processing one or more semiconductor layers on the support substrate to make a completed semiconductor device. A patterned release layer and, optionally, a capping layer are disposed on or over the completed semiconductor device and the patterned release layer or capping layer, if present, are bonded to a handle substrate with a bonding layer. The support substrate is removed to expose the completed semiconductor device and, in some embodiments, a portion of the patterned release layer. In some embodiments, an entry path is formed to expose a portion of the patterned release layer. In some embodiments, the release layer is etched and the completed semiconductor devices transfer printed (e.g., micro-transfer printed) from the handle substrate to a destination substrate.
