Abstract
A semiconductor device includes: a die having die connectors at a front side of the die; a molding material around the die; and a redistribution structure, where the die connectors of the die are attached to a first side of the redistribution structure, where the redistribution structure includes: a dielectric layer; a conductive line extending along a first surface of the dielectric layer facing the die; and a warpage tuning layer contacting and extending along a first surface of the conductive line facing the die, where a first coefficient of thermal expansion (CTE) of the conductive line is smaller than a second CTE of the warpage tuning layer.
