New Processes Define New Power Plans


By Pallab Chatterjee FinFETs, stacked die, heterogeneous interposers, TSVs, 450mm wafers, new interconnects and everything with MEMs and sensors is what the last few weeks have brought. A number of major announcements, technology releases, conference updates have identified these technologies as the future of IC design. At ISQED, Robert Geer, chief academic officer at the College of Nanosca... » read more

Business First


The move to stacked die poses some interesting technology challenges and promises significant technology benefits, but the real driver is business—and for this market to work, it has to continue being about business. In the past it was technology first, business last. We are now at the stage where it is business first, technology last. Re-use of entire die as subystems, better use of desig... » read more

New Stacking Issues


Reduced form factors, higher performance, and the demand for lower power necessitate the need for 3D-IC/silicon interposer designs with through-silicon vias (TSVs). That also creates major design challenges in three areas. The verification of power, signal, and reliability integrity—particularly with multi-stacked die on silicon interposer with TSVs—presents issues that can only be overcome... » read more
