Patent ID: 8349649

Claim:
A method of manufacturing a semiconductor device comprising: providing a first interposer in which a first chip first interconnection is formed; providing a first chip having a circuit forming surface on which a circuit element is formed; providing a second interposer in which a first chip second interconnection is formed; providing a second chip group; forming a through electrode in said first chip to pass from a principal surface to a back surface; mounting said second chip group on a principal surface of said second interposer; arranging said first chip on a back surface of said second interposer such that said first chip second interconnection is electrically connected with said circuit element; and arranging said first chip on said first interposer such that said first chip first interconnection is electrically connected with said circuit element, wherein one of said first chip first interconnection and said first chip second interconnection is electrically connected with said circuit element through said through electrode, wherein said providing a second interposer comprises forming said second interposer on a support member, wherein said mounting said second chip group is performed after said forming said second interposer on said support member, wherein said arranging said first chip on a back surface of said second interposer comprises separating said support member from said second interposer; and arranging said first chip on the back surface of said second interposer after said separating.
