Abstract:
A method of forming a multiple semiconductor device stackapparatus comprising: providing a substrate; providing a first semiconductor device having at least one bond pad on an active surface thereof; mounting and electrically connecting said first semiconductor device to said substrate; providing a first interposer device; mounting said first interposer device to said first semiconductor device, on a side opposite said substrate, said first interposer device having a first surface of a first area and a second surface of a second area less than said first area with a first pair of recesses formed on opposing edges of said first interposer device thus exposing said at least one bond pad on said active surface of said first semiconductor device, said second surface mounted to said active surface of said first semiconductor device; providing a second semiconductor device; and mounting said second semiconductor device on said first surface of said first interposer device, opposite said first semiconductor device and electrically connecting said second semiconductor device to either said first semiconductor device or to said substrate or both.
