Original Abstract Submitted
a semiconductor package includes: a first redistribution structure including a first insulating layer and first conductive patterns; a connection substrate on the first redistribution structure, and including a base layer and a through electrode penetrating the base layer, wherein the base layer includes a first material; a molding layer at least partially surrounding the connection substrate and disposed on the first redistribution structure, wherein the molding layer includes a second material; a second redistribution structure disposed on the molding layer and the connection substrate; and a plurality of semiconductor devices spaced apart from each other on the second redistribution structure, wherein a first thermal expansion coefficient of the first material of the base layer is less than a second thermal expansion coefficient of the second material of the molding layer, and wherein an upper surface of the base layer is substantially coplanar with an upper surface of the molding layer.
