Classification: CPC H | IPC H

Claim 18:
19. A method for manufacturing an LED device, comprising the steps of:
1) Providing an epitaxial structure that includes a first-type semiconductor unit having a contact surface, an active layer disposed on the first-type semiconductor unit opposite to the contact surface, and a second-type semiconductor unit disposed on the active layer opposite to the first-type semiconductor unit and having a light emitting surface opposite to the first-type semiconductor unit;
2) Forming a light transmittable dielectric element on the contact surface of the first-type semiconductor unit, the light transmittable dielectric element being formed with at least one first through hole to expose the contact surface, and subsequently forming an adhesive layer on a surface of the light transmittable dielectric element opposite to the first-type semiconductor unit, the adhesive layer being formed with at least one second through hole that is in spatial communication with and corresponds in position to the first through hole, and having a thickness that is at most one fifth of a thickness of the light transmittable dielectric element, the adhesive layer being made of a transparent electrically conductive material;
3) Forming a metal contact element on a surface of the adhesive layer opposite to the light transmittable dielectric element, the metal contact element extending into the first and second through holes and electrically contacting the contact surface of the first-type semiconductor unit.
