The disclosed technology provides micro-assembled micro-LED displays and lighting elements using arrays of micro-LEDs that are too small (e.g., micro-LEDs with a width or diameter of 10 μm to 50 μm), numerous, or fragile to assemble by conventional means. The disclosed technology provides for micro-LED displays and lighting elements assembled using micro-transfer printing technology. The micro-LEDs can be prepared on a native substrate and printed to a display substrate (e.g., plastic, metal, glass, or other materials), thereby obviating the manufacture of the micro-LEDs on the display substrate. In certain embodiments, the display substrate is transparent and/or flexible.

Micro assembled LED displays and lighting elements

A overhanging device cavity structure comprises a substrate and a cavity disposed in or on the substrate. The cavity comprises a first cavity side wall and a second cavity side wall opposing the first cavity side wall on an opposite side of the cavity from the first cavity side wall. A support extends from the first cavity side wall to the second cavity side wall and at least partially divides the cavity. A device is disposed on, for example in direct contact with, the support and extends from the support into the cavity.

Overhanging device structures and related methods of manufacture

A component structure comprises a substrate and a sacrificial layer comprising a sacrificial material disposed on or in the substrate. The sacrificial layer defines sacrificial portions laterally spaced apart by anchors. A component is disposed entirely over each sacrificial portion and connected to at least one anchor by a tether. A spacer comprising a spacer material is disposed in or on the sacrificial portion at least partially between the tether and the substrate. For at least one etchant, the spacer material etches faster than the sacrificial material when exposed to the etchant.
