Wafer scale integration-a technology whose time has come

The criteria which every new technological advance needs to satisfy before it can become accepted into the mainstream of product development are identified. it is then suggested that one company´s wafer scale integration (WSI) now satisfies these criteria; it meets the needs of the intermediate storage market, and it is cost effective to manufacture because it provides a way for semiconductor manufacturers to achieve high yields quickly, without the need for additional capital expenditure. The product road map for WSI is described
