Claim 17:
18. A chip package comprising:
a solid layer having a first surface and a second surface opposite to said first surface, wherein said solid layer comprises a compound of silicon and oxygen, wherein said solid layer has a thickness between 50 and 150 micrometers, wherein said solid layer comprises a first region and a second region between said first region and a first edge of said solid layer;
a plurality of copper posts in a plurality of through holes in said second region respectively;
a first interconnection scheme over said first surface, wherein said first interconnection scheme comprises first and second metal interconnects over said first surface, and a first polymer layer over said first and second metal interconnects, wherein said first metal interconnect is connected to a first copper post of said plurality of copper posts, wherein said first metal interconnect comprises a first metal layer and a first copper layer over said first metal layer;
a first semiconductor chip over said first interconnection scheme, wherein said first semiconductor chip comprises a third metal interconnect under a first metal pad of said first semiconductor chip, wherein said third metal interconnect comprises a second metal layer under said first metal pad and a second copper layer under said second metal layer, wherein said second copper layer has a thickness between 5 and 30 micrometers, wherein said first semiconductor chip is coupled to a second copper post of said plurality of copper posts through said third metal interconnect;
a second semiconductor chip over said first interconnection scheme, wherein said second semiconductor chip comprises a second metal pad coupled to said second metal interconnect;
a third semiconductor chip under said first interconnection scheme; and
a plurality of metal bumps under said second surface, wherein one of said plurality of metal bumps comprises a tin-containing layer.
