发明名称 Laminated semiconductor wafer, laminated chip package and method of manufacturing the same
摘要 In a laminated semiconductor substrate, a plurality of semiconductor substrates are laminated. Each of the semiconductor substrate has a plurality of scribe-groove parts formed along scribe lines. Further, each of the semiconductor substrate has a plurality of device regions insulated from each other and has a semiconductor device formed therein. Further, an uppermost substrate and a lowermost substrate have electromagnetic shielding layer formed in regions other than the scribe-groove parts using a ferromagnetic body. Further, in the laminated semiconductor substrate, a through hole which penetrates the plurality of semiconductor substrates laminated in a laminated direction is formed in the scribe-groove part, and the laminated semiconductor substrate has a through electrode penetrating the plurality of semiconductor substrates through the through hole.
