High Quality Content by WIKIPEDIA articles! Wafer-scale integration, WSI for short, is a yet-unused system of building very-large integrated circuit networks that use an entire silicon wafer to produce a single "super-chip". Through a combination of large size and reduced packaging, WSI could lead to dramatically reduced costs for some systems, notably massively parallel supercomputers. The name is taken from the term very-large-scale integration, the current state of the art when WSI was being developed.
