Patent ID: 7064005

Claim:
A method of manufacturing a semiconductor apparatus constituting a multichip module wherein a plurality of device chips are flip-chip mounted on an interposer substrate, characterized by comprising: a first step for forming an embedded electrode by filling a contact hall penetrating through a wafer with conductor, said wafer being a base material of said interposer substrate; a second step for forming wiring including a connection electrode connected to a first end of the embedded electrode and a connection electrode on which said device chips to be flip-chip mounted on a surface of said wafer; a third step for forming said interposer substrate by grinding and polishing a back surface of said wafer until a second end of said embedded electrode is exposed after said plurality of device chips are flip-chip mounted on said connection electrode formed in the second step; and a fourth step for providing a bump electrode on the second end of said embedded electrode exposed in the third step.
