Wafer-scale integration
System of building very-large integrated circuit networks / From Wikipedia, the free encyclopedia
This article is about the system of building very-large integrated circuit networks. For WaferScale Integration Inc. (Fremont, Calif.), a vendor of EPROM and programmable system-chips acquired by STM, see STMicroelectronics § WaferScale Integration Inc.
Wafer-scale integration (WSI) is a system of building very-large integrated circuit (commonly called a "chip") networks from an entire silicon wafer to produce a single "super-chip". Combining large size and reduced packaging, WSI was expected to lead to dramatically reduced costs for some systems, notably massively parallel supercomputers but is now being employed for deep learning. The name is taken from the term very-large-scale integration, the state of the art when WSI was being developed.
