US 2005/0032259 A1 · Display system and method of producing the same

Abstract

Disclosed are a display system and a method of producing the same. In the present invention, a hexagonal pyramid shaped GaN semiconductor light-emitting device selectively crystal-grown is fixed on an upper surface of a substrate by embedding it in an insulation layer formed of an epoxy resin. Then the insulation layer is selectively dry etched in an oxygen plasma atmosphere to expose an upper end portion of the GaN semiconductor light-emitting device. A conductor film is formed on the entire surface, and a required portion of the conductor film is left as a lead-out electrode while the unrequired portion is removed by lithography.

Dependent claims

A method of producing a display system by disposing and fitting a plurality of semiconductor light-emitting devices on a substrate surface, comprising the steps of:

embedding said semiconductor light-emitting devices in an insulation layer,
selectively or non-selectively thinning said insulation layer to expose upper end portions of said semiconductor light-emitting devices, wherein a planar surface of the insulation layer is coplanar with the exposed upper end portion;
and
forming a conductor film on said exposed upper end portions,
whereby upper end portion electrodes of said semiconductor light-emitting devices are led out to an upper surface of said insulation layer.
