Abstract
A three dimensional device stack structure comprises two or more active device and interconnect layers further connected together using through substrate vias. Methods of forming the three dimensional device stack structure comprise alignment, bonding by lamination, thinning and post thinning processing. The via features enable the retention of alignment through the lamination process and any subsequent process steps thus achieving a mechanically more robust stack structure compared to the prior art.
