Claim 12:
13. A method, comprising:
forming an epitaxial layer on a starter substrate attaching the epitaxial layer onto a first carrier substrate;
etching away the starter substrate;
attaching the epitaxial layer onto a second carrier substrate;
moving the first carrier substrate away from the epitaxial layer;
etching away part of the epitaxial layer to form a plurality of light emitting diode (LED) dies on the epitaxial layer;
forming device-side bumps the plurality of LED dies;
forming backplane-side bumps on at least one of one or more pre-determined locations on a backplane, the at least one of one or more pre-determined locations corresponding to the one or more selected LED dies of the plurality of LED dies;
establishing one or more conductive bonds between the device-side bumps on the one or more selected LED dies and the corresponding backplane-side bumps on the backplane; and
moving the second carrier substrate away from the backplane to transfer the one or more LED dies to the backplane.
