Abstract
According to one embodiment, a first electrode is formed on a first face of a first semiconductor chip, and a second electrode and a protrusion are formed on a second face of a second semiconductor chip. The first semiconductor chip and the second semiconductor chip are spaced from one another by the protrusion in such a manner that the first face and the second face face each other. The first semiconductor chip and the second semiconductor chip are subject to reflow to be electrically connected to each other, and then the protrusion is cured at a temperature lower than a reflow temperature.
