Claim:
1. An integrated circuit device, comprising: an interposer structure and two or more active components carried by said interposer structure, and said interposer structure includes an interposer substrate including a certain semi-conductor material and a plurality of vias formed in the substrate; wherein said two or more active components include at least two components, which are respectively constructed of at least two different semiconductor materials, carried by at least two different respective regions of the interposer structure, said two or more active components include at least one active component, whose semi-conductor materials are different than the certain semi-conductor material of the interposer substrate and have a coefficient of thermal expansion (CTE) different than a CTE of the certain semi-conductor material of the interposer substrate; wherein said interposer structure includes at least two different respective arrangements of the vias in said at least two different respective regions of the interposer structure, at which said at least two components of the at least two different semiconductor materials are located; wherein said vias having CTEs substantially different than the CTE of the interposer substrate; and wherein configurations of said at least two different arrangements of the vias are different with respect to at least one parameter of the arrangements such that effective CTEs of the interposer structure, including the interposer substrate and the arrangements of vias at said at least two different respective regions, respectively match the CTEs of the semiconductor materials of the respective at least two components that are carried by the interposer structure at said at least two regions respectively, thereby providing that said interposer structure with said at least two active components of the at least two different semiconductor materials being mechanically stable under varying temperature conditions.
