摘要: Provided is a semiconductor package with enhanced reliability and a method of manufacturing the same. The semiconductor package includes a package substrate including a body layer having a central area and a peripheral area, a first protective layer on a top surface of the body layer, and a second protective layer on the first protective layer in the peripheral area, a semiconductor chip mounted on the first protective layer in the central area in a flip-chip structure, an underfill in a gap between the first protective layer and the semiconductor chip and in a gap between the connection terminals, an interposer on the semiconductor chip, and inter-substrate connection terminals on the peripheral area of the package substrate and electrically connecting the package substrate to the interposer, where the underfill has an anchor structure extending into the first protective layer.

摘要: A solder reflow apparatus may include a reflow chamber, a heater and a stage. The reflow chamber may be configured to receive a heat transfer fluid. The heat transfer fluid may be configured for transferring heat to a solder for mounting an electronic part on a substrate. The heater may be configured to heat the heat transfer fluid in the reflow chamber. The stage may be in the reflow chamber to support the substrate. The stage may be inclined to a bottom surface of the reflow chamber to induce the heat transfer fluid toward a central portion of the substrate. Thus, the vertically ascended heat transfer fluid may be uniformly applied to the central portion and an edge portion of the substrate so that the solders at the central portion and the edge portion of the substrate may be uniformly soldered.
