GLOBALFOUNDRIES Fab 8 Adds Tools to Enable 3D Chip Stacking at 20nm and Beyond

GLOBALFOUNDRIES today announced a significant milestone on the road to enabling 3D stacking of chips for next-generation mobile and consumer applications. At its Fab 8 campus in Saratoga County, NY, the company has begun installation of a special set of production tools to create Through-Silicon Vias (TSVs) in semiconductor wafers processed on the company's leading-edge 20nm technology platform. The TSV capabilities will allow customers to stack multiple chips on top of each other, providing another avenue for delivering the demanding requirements of tomorrow's electronic devices.

Essentially vertical holes etched in silicon and filled with copper, TSVs enable communication between vertically stacked integrated circuits. For example, the technology could allow circuit designers to place stacks of memory chips on top of an application processor, which can dramatically increase memory bandwidth and reduce power consumption-a key challenge for designers of the next generation of mobile devices such as smartphones and tablets.
