Abstract:
1. A multichip light emitting diode (LED), comprising: a plurality of LED chips fabricated on a wafer, the plurality of LED chips consisting of a blue LED chip, a red LED chip, a green LED chip, and a target LED chip, wherein the plurality of LED chips are in electrical contact with each other via a metal line; a set of conformal coatings that cover an isolated active area of each of the plurality of LED chips fabricated on the wafer, wherein each conformal coating of the set of conformal coatings comprises a phosphor and silicon ratio producing colors selected from a group consisting of yellow, green, and red that is based on a measurement of a wavelength of a light output that is particular to an LED chip of the plurality of LED chips that is covered by the each conformal coating; and wherein a light output of the target LED chip is converted to white light using the set of conformal coatings.
