Abstract:
1. A method of manufacturing a system in a package (SIP) type semiconductor device, comprising: providing a sacrificial silicon substrate; forming an insulation layer over the sacrificial silicon substrate; forming a first passivation layer over the insulation layer and sacrificial silicon substrate; forming an integrated passive circuit over the first passivation layer by, forming a second passivation layer over the integrated passive circuit; mounting a plurality of system components over the second passivation layer in electrical contact with the second conductive layer; depositing an encapsulant over the second passivation layer and system components, the encapsulant having a coefficient of thermal expansion (CTE) matching a CTE of the system components; removing the sacrificial silicon substrate and insulation layer; etching an opening in the first passivation layer; and depositing bumps in the opening of the first passivation layer in electrical contact with the first conductive layer.
