Abstract
An optical emitter includes a Light-Emitting Diode (LED) on a package wafer, transparent insulators, and one or more transparent electrical connectors between the LED die and one or more contact pads on the packaging wafer. The transparent insulators are deposited on the package wafer with LED dies attached using a lithography or a screen printing method. The transparent electrical connectors are deposited using physical vapor deposition, chemical vapor deposition, spin coating, spray coating, or screen printing and may be patterned using a lithography process and etching.
