Abstract

An electronic package and a method for fabricating an electronic package are provided. An encapsulation layer encapsulates a first electronic component and a plurality of conductive pillars, and is defined with a reservation region and a removal region adjacent to the reservation region. A circuit structure is disposed on the encapsulation layer. The removal region and the circuit structure therewithin are removed for an optical communication element to protrude from a lateral surface of the encapsulation layer when the optical communication element is disposed on the circuit structure, so as to avoid a packaging material used in a subsequent process from being adhered to a protruding portion of the optical communication element.

Claims (31)

1. An electronic package, comprising:

an encapsulation layer having a first surface, a second surface opposing the first surface, and a lateral surface adjacent to the first surface and the second surface;

a first electronic component embedded in the encapsulation layer;

a plurality of conductive pillars embedded in the encapsulation layer;

a circuit structure disposed on the first surface of the encapsulation layer and electrically connected to the conductive pillars and the first electronic component; and

an optical communication element disposed on the circuit structure and electrically connected to the circuit structure,

wherein the optical communication element has an opto-electronic part and a laser part.

2. The electronic package of claim 1 , wherein the first electronic component is bonded and electrically connected to a plurality of conductors.

3. The electronic package of claim 1 , wherein the opto-electronic part converts an optical signal into an electric signal, and the laser part converts the electric signal into another optical signal and emits the another optical signal.

4. The electronic package of claim 3 , wherein the optical communication element is electrically connected to the circuit structure via a plurality of conductive bumps disposed outside the laser part.

5. The electronic package of claim 4 , further comprising a packaging material packaging the plurality of conductive bumps and free from being formed on the laser part.

6. The electronic package of claim 1 , wherein the optical communication element has a protruding portion protruding from the lateral surface of the encapsulation layer and acting as a connecting segment.

7. The electronic package of claim 1 , further comprising a circuit part disposed on the second surface of the encapsulation layer and electrically connected to the conductive pillars.

8. The electronic package of claim 7 , further comprising a plurality of conductive elements disposed on the circuit part.

9. The electronic package of claim 1 , further comprising a carrier structure disposed on the second surface of the encapsulation layer.

10. The electronic package of claim 9 , further comprising a second electronic component disposed on the carrier structure.

11. A method for fabricating an electronic package, comprising:

encapsulating a first electronic component and a plurality of conductive pillars with an encapsulation layer having a first surface and a second surface opposing the first surface and being defined with a reservation region and a removal region adjacent to the reservation region, wherein the first electronic component and a portion of the conductive pillars are disposed within the reservation region, and a remaining of the conductive pillars are disposed within the removal region;

disposing a circuit structure on the first surface of the encapsulation layer, and electrically connecting the circuit structure to the conductive pillars and the first electronic component;

disposing a circuit part on the second surface of the encapsulation layer, and electrically connecting the circuit part to the conductive pillars;

removing the removal region and the circuit structure and the circuit part within the removal region, and forming a lateral surface of the encapsulation layer adjacent to the first surface and the second surface; and

disposing on the circuit structure an optical communication element having an opto-electronic part and a laser part, and electrically connecting the optical communication element to the circuit structure.

12. The method of claim 11 , wherein the first electronic component is bonded and electrically connected to a plurality of conductors.

13. The method of claim 11 , wherein the plurality of conductive pillars surround the first electronic component before removing the removal region.

14. The method of claim 11 , wherein the opto-electronic part converts an optical signal into an electric signal, and the laser part converts the electric signal into another optical signal and emits the another optical signal.

15. The method of claim 14 , wherein the optical communication element is electrically connected to the circuit structure via a plurality of conductive bumps disposed outside the laser part.

16. The method of claim 15 , further comprising packaging the plurality of conductive bumps with a packaging material free from being formed on the laser part.

17. The method of claim 11 , wherein the optical communication element has a protruding portion protruding from the lateral surface of the encapsulation layer and acting as a connecting segment.

18. The method of claim 11 , further comprising disposing a plurality of conductive elements on the circuit part.

19. The method of claim 11 , further comprising disposing a carrier structure on the second surface of the encapsulation layer.

20. The method of claim 19 , further comprising disposing a second electronic component on the carrier structure.
