Abstract
The present invention discloses a method for fabricating a light emitting diode (LED) package structure. The method comprises the following steps: a carrier having a substrate and a first protrusion is provided, wherein the first protrusion is disposed on the substrate and has a recess. An adhesion layer and a LED chip are disposed on a bottom of the recess, wherein the adhesion layer is bonded between the carrier and the LED chip, and a ratio between a width of the recess and a width of the LED chip is larger than 1 and smaller than or equal to 1.5 such that a gap existing between a sidewall of the LED chip and an inner sidewall of the recess.
