Abstract
A method for forming a light-emitting package structure provided with a predetermined view angle is provided. The method includes the steps of: disposing a flip chip on a carrier substrate; filling an underfill material between at least two electrodes of the flip chip for supporting the flip-chip; laser lifting-off a growing substrate from the flip chip for forming a thin film chip and exposing an epitaxial structure from the thin film chip; roughening the epitaxial structure exposed from the thin film chip; providing a view angle adjusting structure including a wavelength converting layer on the thin film chip, and selecting a predetermined view angle and achieving the predetermined view angle by adjusting the view angle adjusting structure according to a linear regression formula.
