Therefore, the second die 280 is electrically connected to the intermediate substrate 220 or the base substrate 210 via the bonding wires 284.

[0052] As shown in Figure 22, a molded layer 292 is then formed on the first surface 211 of the base substrate 210, covering the intermediate substrate 220, the passive member 282, the first die 250, the second die 280, and the bonding wire 284.

[0053] As shown in Figure 23, a plurality of solder balls 290 are then formed on the second surface 212 of the base substrate 210, and the solder balls 290 are electrically connected to the base substrate 210 to form a semiconductor package as shown in Figure 2.

[0054] The solder ball 290 is electrically connected to the first conductive block 231 via the conductive wires 213 and 214 on the base substrate 210, thereby allowing the first die 250 to be electrically connected to an external circuit using the solder ball 290 via the intermediate substrate 220 and the base substrate 210. Similarly, the solder ball 290 is electrically connected to the bonding wire 284 via the conductive wires 213 and 214 on the base substrate 210, thereby allowing the second die 280 to be electrically connected to an external circuit using the solder ball 290 via the bonding wire 284, the intermediate substrate 220 and the base substrate 210.

[0055] According to the semiconductor package of the present invention, manufacturing costs are reduced and yield is increased.
