Design and test of 2.5D and 3D stacked ICs

Three dimensional chips stacked using Through Silicon Via (TSV) technology has been under consideration and the subject of intensive research for several years now. Soon the technologies will become available through standard fabs. Will the technology be an instant hit, a niche, or a flop? What is needed to ensure it reaches hit status? What are the basic manufacturing steps and flows? This tutorial will discuss these question mainly in the context of the opportunities and challenges that face the designer. What are the significant opportunities presented by 3DIC? What problems will the designer face that will need clever solutions? What are the potential solution paths?
