Abstract: A micro-transfer printable electronic component includes one or more electronic components, such as integrated circuits or LEDs. Each electronic component has device electrical contacts for providing electrical power to the electronic component and a post side. A plurality of electrical conductors includes at least one electrical conductor electrically connected to each of the device electrical contacts. One or more electrically conductive connection posts protrude beyond the post side. Each connection post is electrically connected to at least one of the electrical conductors. Additional connection posts can form electrical jumpers that electrically connect electrical conductors on a destination substrate to which the printable electronic component is micro-transfer printed. The printable electronic component can be a full-color pixel in a display.

Abstract: 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 ?m to 50 ?m), 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.

Abstract: The present invention provides structures and methods that enable the construction of micro-LED chiplets formed on a sapphire substrate that can be micro-transfer printed. Such printed structures enable low-cost, high-performance arrays of electrically connected micro-LEDs useful, for example, in display systems. Furthermore, in an embodiment, the electrical contacts for printed LEDs are electrically interconnected in a single set of process steps. In certain embodiments, formation of the printable micro devices begins while the semiconductor structure remains on a substrate. After partially forming the printable micro devices, a handle substrate is attached to the system opposite the substrate such that the system is secured to the handle substrate. The substrate may then be removed and formation of the semiconductor structures is completed. Upon completion, the printable micro devices may be micro transfer printed to a destination substrate.
