ABSTRACT:
A flip-chip LED package structure is disclosed. The flip-chip LED package structure includes a submount, patterned conductive films, a LED chip and two bumps. Several grooves are formed on the sidewalls of the submount. The patterned conductive films are formed on the grooves. The patterned conductive films extend from the grooves to parts of a top surface and a backside surface of the submount. The bumps are formed on two electrodes of the LED chip. The LED chip is disposed on the submount and connects electrically with the patterned conductive films via the bumps. The flip-chip LED package structure is disposed on a circuit board and connects electrically with the circuit without the wire bonding.
