SEMICONDUCTOR PACKAGES HAVING HEAT DISSIPATION PILLARS

A semiconductor package includes a lower redistribution structure, a first semiconductor chip and a second semiconductor chip that stacked on the lower redistribution structure, the second semiconductor chip including a heat dissipation pad disposed at an upper surface of the second semiconductor chip, a lower conductive pillar disposed on the lower redistribution structure, an upper conductive pillar disposed on the lower conductive pillar, a heat dissipation pillar disposed on the heat dissipation pad, an upper redistribution structure disposed on the upper conductive pillar; and a heat dissipation structure disposed on the heat dissipation pillar.
