LIGHT EMITTING DIODE PACKAGE STRUCTURE AND MANUFACTURING METHOD THEREOF
First Claim
1. A method of fabricating a light emitting diode (LED) package structure, comprising:
- providing at least one LED chip, wherein the LED chip is electronically connected with a carrier and has a light emitting surface and a plurality of side surfaces connected to the light emitting surface;
providing a first mask, wherein the first mask has at least one first opening positioned related to the LED chip;
providing a spray coating apparatus, wherein the spray coating apparatus is disposed above the first mask to perform a first spray coating process, and the spray coating apparatus moves back and forth to spray a first phosphor solution over the LED chip so that the light-emitting surface and the side surfaces of the LED chip can be conformally covered by the sprayed first phosphor solution;
performing a curing process to cure the first phosphor solution to form a first fluorescent layer; and
forming a molding compound to encapsulate the first fluorescent layer and a portion of the carrier.

Abstract
A method of fabricating a light emitting diode (LED) package structure is provided. A carrier and at least one LED chip having a light emitting surface and a plurality of side surfaces are provided. A first mask having at least one first opening is provided, and the first opening at least exposes the LED chip. A spray coating apparatus is provided above the first mask to perform a first spray coating process. The spray coating apparatus moves back and forth to spray a first phosphor solution over the LED chip so that the light-emitting surface and the side surfaces of the LED chip can be conformally covered by the sprayed first phosphor solution. The first phosphor solution is cured to form a first fluorescent layer by performing a curing process. A molding compound is formed to encapsulate the first fluorescent layer and a portion of the carrier.
