Abstract:
The disclosed technology relates generally to methods and systems for controlling the release of micro devices. Prior to transferring micro devices to a destination substrate, a native substrate is formed with micro devices thereon. The micro devices can be distributed over the native substrate and spatially separated from each other by an anchor structure. The anchors are physically connected/secured to the native substrate. Tethers physically secure each micro device to one or more anchors, thereby suspending the micro device above the native substrate. In certain embodiments, single tether designs are used to control the relaxation of built-in stress in releasable structures on a substrate, such as Si ( 1 0 0 ). Single tether designs offer, among other things, the added benefit of easier break upon retrieval from native substrate in micro assembly processes. In certain embodiments, narrow tether designs are used to avoid pinning of the undercut etch front.

Claim (Index 21):
A method of fabricating a printable component array, the method comprising:\n forming a sacrificial layer comprising silicon ( 1   0   0 ) sacrificial material on a process side of a source substrate; forming a plurality of releasable micro objects at least in part on the sacrificial layer; forming an anchor structure on the source substrate that remains rigidly attached to the source substrate in the absence of the sacrificial material; and forming a plurality of tethers, wherein each tether of the plurality of tethers laterally connects a releasable micro object of the plurality of releasable micro objects to a portion of one of the anchor structures, each tether of the plurality of tethers is located center on an anchor-facing edge of the respective releasable micro object of the plurality of releasable micro objects, and each tether is shaped to fracture in response to movement of the releasable micro object, so that in the absence of the sacrificial material:\n the releasable micro objects move with respect to the anchor structures; \n the tethers deform and are mechanically stressed; and \n each tether of the plurality of tethers remains rigidly attached to both a respective anchor and a respective releasable micro object of the plurality of micro objects, thereby preserving the spatial configuration of the plurality of releasable micro objects with respect to the source substrate.
