Abstract:
1. A substrate-free semiconducting sheet, comprising: an array of semiconducting elements bonded to a matrix material to form a thin film; said semiconducting elements including at least one light emitting diode chip, at least one photovoltaic chip, at least one solar cell chip, at least one wavelength conversion chip, at least one transistor chip, at least one diode chip, or at least one charge storage device; wherein each of said semiconducting elements has a first surface, a second surface and one or more edge surfaces that connect said first surface and said second surface; wherein said matrix material is bonded to said edge surfaces of said semiconducting elements; wherein said substrate-free semiconducting sheet is substantially the same thickness as said semiconducting elements; and wherein said semiconductor element is at least one light emitting diode chip, said at least one light emitting diode chip is substrate-free and said at least one light emitting diode chip is at least 10 microns thick.
