Claim Text:
1. A method of making a semiconductor device, comprising: providing a silicon substrate capable of sustaining temperatures equal to or greater than 200° C.; forming an interconnect structure over the silicon substrate at temperatures equal to or greater than 200° C. by, disposing a semiconductor die over the interconnect structure; depositing a first encapsulant over the semiconductor die with the first encapsulant disposed over a surface of the semiconductor die opposite the interconnect structure and between the semiconductor die and interconnect structure; removing a portion of the first encapsulant to planarize the first encapsulant with the surface of the semiconductor die; depositing a second encapsulant over semiconductor die and first encapsulant; removing the silicon substrate from over the wetting layer of the multi-layer UBM and insulating layer after disposing the semiconductor die over the interconnect structure; and forming a plurality of first conductive bumps contacting the wetting layer of the multi-layer UBM.
