Patent ID: 8394706

Claim:
A method for registered assembly of a plurality of printable semiconductor elements on a receiving surface of a substrate, said method comprising the steps of: providing a plurality of printable semiconductor structures having preselected spatial orientations relative to each other; wherein each of said printable semiconductor structures comprises a printable semiconductor element, and a bridge element connected to said printable semiconductor element and connected to a mother wafer, wherein each of said printable semiconductor elements and said bridge elements are at least partially undercut from said mother wafer; contacting said printable semiconductor elements with a transfer device having a contact surface, wherein contact between said contact surface and said printable semiconductor elements binds at least a portion of said printable semiconductor elements to said contact surface of said transfer device; moving said transfer device in a manner resulting in the fracture of at least a portion of said bridge elements, thereby providing for registered transfer of at least a portion of said printable semiconductor elements from said mother wafer to said transfer device, thereby forming said contact surface having at least a portion of said printable semiconductor elements disposed thereon; contacting said receiving surface of said substrate with said printable semiconductor elements disposed on said contact surface; and separating said contact surface of said transfer device and said printable semiconductor elements, wherein said printable semiconductor elements are transferred onto said receiving surface, thereby providing for registered assembly of said plurality of printable semiconductor elements on said receiving surface of said substrate.
