Abstract: A chip packaging structure includes a chip, a redistribution layer, a solder ball, an encapsulant, and a stress buffer layer. The chip has an active surface and a back surface opposite to each other, and a peripheral surface connected to the active surface and the back surface. The redistribution layer is disposed on the active surface of the chip. The solder ball is disposed on the redistribution layer, and the chip is electrically connected to the solder ball through the redistribution layer. The encapsulant encapsulates the active surface and the back surface of the chip, the redistribution layer, and part of the solder ball. The stress buffer layer at least covers the peripheral surface of the chip. An outer surface of the stress buffer layer is aligned with a side surface of the encapsulant.

Abstract: A vapor chamber device and a manufacturing method are disclosed. The vapor chamber has a housing and multiple independent chambers. The housing includes two shells opposite to each other. The independent chambers are formed between the two shells. Each independent chamber contains a working fluid and has at least one diversion bump and a capillary structure. The diversion bump is formed on an inner surface of the second shell, and the capillary structure is mounted on the diversion bump. When the vapor chamber device is vertically mounted to a heat source, the independent chambers at an upper portion of the vapor chamber device still contain the working fluid. The working fluid in the independent chambers may not all flow to a bottom of the vapor chamber device. Therefore, a contact area between the working fluid and the heat source is increased and heat dissipation efficiency is improved.
