Abstract
The disclosure provides an electronic package and a method of manufacturing the same. The method is characterized by encapsulating an electronic component with a packaging layer and forming on an upper surface of the packaging layer a circuit structure that is electrically connected to the electronic component; and forming a stress-balancing layer on a portion of the lower surface of the packaging layer to balance the stress exerted on the upper and lower surfaces of the packaging layer, thereby reducing the overall package warpage and facilitating the manufacturing process.
Claims8
A method for manufacturing an electronic package, comprising:
- providing at least one electronic component on a carrier;
- forming a packaging layer on the carrier to encapsulate the electronic component, the packaging layer including a first surface and a second surface opposite to the first surface and being bonded to the carrier via the first surface;
- forming a stress-balancing layer on a portion of the second surface of the packaging layer;
- removing the carrier;
- forming on the first surface of the packaging layer a circuit structure electrically connected with the electronic component, wherein the stress-balancing layer is free from being electrically connected with the circuit structure;
- and
- forming an encapsulating layer on the second surface of the packaging layer,
- wherein the encapsulating layer encapsulates the stress-balancing layer, and
- wherein the encapsulating layer is fully integrated with the packaging layer such that there is no interface between the encapsulating layer and the packaging layer.
