1. A method for producing a light emitting diode (LED), comprising:
- forming an LED on a substrate;
measuring a base emission characteristic of the formed LED;
developing a compensation scheme by selecting a group of candidate phosphors based on the base emission characteristic of the formed LED, wherein the group of the candidate phosphors is selected based on a distribution area in chromaticity plot;
selecting a plurality of phosphors, from the group of the candidate phosphors, based on the measured base emission characteristic of the formed LED such that a combined emission from the LED is closer to white light than the base emission characteristic; and
introducing the selected phosphors onto the LED.

Abstract
Several embodiments of semiconductor systems and associated methods of color corrections are disclosed herein. In one embodiment, a method for producing a light emitting diode (LED) includes forming an (LED) on a substrate, measuring a base emission characteristic of the formed LED, and selecting a phosphor based on the measured base emission characteristic of the formed LED such that a combined emission from the LED and the phosphor at least approximates white light. The method further includes introducing the selected phosphor onto the LED via, for example, inkjet printing.
