Claim:
1. A method of fabricating a semiconductor package, comprising: providing at least a semiconductor structure having an interposer and a first semiconductor element disposed on the interposer; disposing the semiconductor structure on a carrier having an insulation layer and a supporting portion, with the interposer being supported by the supporting portion, wherein the supporting portion and the first semiconductor element are disposed on and in direct contact with the insulation layer; carrying out a first test process to test an electrical performance between the interposer and the first semiconductor element so as to determine if the interposer is defective, and if the interposer is defective, separating the interposer from the first semiconductor element and disposing the first semiconductor element on a new interposer that is determined to be good by the first test process; removing the insulation layer and the supporting portion when the interposer and the first semiconductor element are determined to be good by the first test process; disposing at least a second semiconductor element on the interposer side-by-side with the first semiconductor element; carrying out a second test process to test an electrical performance between the interposer and the second semiconductor element so as to determine if the interposer is defective, and if the interposer is defective, separating the interposer from the first semiconductor element and the second semiconductor element, and disposing the first semiconductor element and the second semiconductor element on another new interposer that is determined to be good by the second test process; and disposing the interposer with the first semiconductor element and the second semiconductor element on a package substrate when the interposer, the first semiconductor element, and the second semiconductor element are determined to be good by the second test process.
