Abstract

See full text

A method of forming an inorganic light emitting diode (LED) with a via contact scheme for large-area display and backlighting applications is provided. An inorganic LED stack comprising, from bottom to top, a first contact layer, an active layer, and a second contact layer having a polarity different from the first contact layer is removed from the underlying base substrate by a controlled spalling or chemical liftoff process. A via contact scheme that can provide ohmic contacts to both the first contact layer and the second contact layer is then formed on the released LED stack.
