Abstract: A semiconductor package includes a redistribution structure including a redistribution layer including copper (Cu) and an insulating layer surrounding the redistribution layer, a semiconductor chip mounted on the redistribution structure and including connection pads, internal connection terminals between the redistribution structure and the semiconductor chip electrically connecting the redistribution layer to the connection pads, external connection terminals attached under the redistribution structure and electrically connected to the redistribution layer, and an encapsulant configured to surround the semiconductor chip and the internal connection terminals on the redistribution structure. The insulating layer includes an insulating material of which K is 20 to 100 in a TC index according to equation below. K = U T ( α 1 - α 2 ) × Δ ⁢ T × E [ TC ⁢ INDEX ]

Abstract: Disclosed are semiconductor packages and their fabrication methods. The semiconductor package includes a redistribution substrate that includes an organic dielectric layer and a metal pattern in the organic dielectric layer, and a semiconductor chip on the redistribution substrate. The organic dielectric layer has a maximum absorbance equal to or greater than about 0.04 at a first wavelength range, and a fluorescence intensity equal to or greater than about 4×103 at the first wavelength range. The first wavelength range is about 450 nm to about 650 nm.
