Claim 12:
13. A micro-device structure, comprising:
a source substrate having a sacrificial layer comprising a sacrificial portion adjacent to an anchor portion; and
a micro-device, comprising a micro-device substrate, disposed completely over the sacrificial portion, the micro-device substrate having a top side opposite the sacrificial portion and a bottom side adjacent to the sacrificial portion and comprising an etch hole that extends entirely through an interior portion of the micro-device substrate from the top side to the bottom side; and
a tether that physically connects the micro-device to the anchor portion,
wherein the etch hole is in contact with the sacrificial portion and exposes at least a portion of the sacrificial portion,
wherein the etch hole and the micro-device are both rectangular, the etch hole has an etch-hole edge, the micro-device has a micro-device edge, and the etch-hole edge is substantially parallel to the micro-device edge.
