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 1 1). 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 30):
A method of fabricating a plurality of transferable micro objects, comprising:\n forming a sacrificial layer comprising 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; applying a polymer layer over the plurality of releasable micro objects and at least a portion of the source substrate, wherein the polymer layer encapsulates the plurality of releasable micro objects; treating the polymer layer to form:\n (i) a plurality of anchor structures on the source substrate for the plurality of transferable micro objects, \n (ii) at least one tether between each transferable micro object and a pre-determined anchor structure of the plurality of anchor structures, and \n (iii) for each of the releasable micro objects, a port of ingress in the polymer layer to a portion of the sacrificial layer underneath a respective transferable micro object; and \n removing at least a portion of the sacrificial layer underneath the plurality of releasable micro objects.
