    Abstract: A semiconductor device includes a semiconductor die. An interconnect structure is formed over an active surface of the semiconductor die. An encapsulant is formed over the semiconductor die and interconnect structure including a first surface opposite the interconnect structure. A peripheral portion of the first surface includes a first roughness disposed outside a footprint of the semiconductor die. A semiconductor die portion of the first surface includes a second roughness less than the first roughness disposed over the footprint of the semiconductor die. The first surface of the encapsulant is disposed within a mold and around the semiconductor die to contact a surface of the mold that includes a third roughness equal to the first roughness and a fourth roughness equal to the second roughness. The first roughness includes a roughness of less than 1.0 micrometers. The second roughness includes a roughness in a range of 1.2-1.8 micrometers.
