The present disclosure provides a semiconductor package including a bottom package having a substrate, a radio-frequency (RF) die and a system-on-a-chip (SoC) die arranged on the substrate in a side-by-side manner, a molding compound covering the RF die and the SoC die, and an interposer over the molding compound. Connection elements and a column of signal interference shielding elements are disposed on the substrate. The connection elements surround the SoC die. The column of signal interference shielding elements is interposed between the RF die and the SoC die. A top package is mounted on the interposer.
