The fabless model was traditionally enabled through clean interfaces – both in technical and business terms – between foundries and fabless semiconductor companies. However, with advanced geometry and analog/mixed-signal process nodes, the technical challenges have been greatly magnified, so that successful semiconductor design requires intimate cooptimization of design and manufacturing, infringing upon those clean interfaces. The panel presents views to these challenges and specifically how companies are planning to address them. Categories and Subject Descriptors B.m Miscellaneous General Terms: Management
