Abstract
A semiconductor package includes a substrate having thereon a high-frequency chip and a circuit component susceptible to high-frequency signal interference; a ground pad on the and between the high-frequency chip and the circuit component; a metal-post reinforced glue wall on the ground pad; a molding compound surrounding the metal-post reinforced glue wall and surrounding the high-frequency chip and the circuit component; and a conductive layer disposed on the molding compound and in contact with the metal-post reinforced glue wall. The metal-post reinforced glue wall comprises first metal posts and glue attached to the first metal posts. An interface between a base of each of the first metal posts and the ground pad has a root mean square (RMS) roughness that is less than 1.0 micrometer.
