Chipmakers are reaching various and challenging inflection points. In logic, many IC makers face a daunting transition from planar transistors at 20nm to finFETs at 14nm. And on another front, the industry is nearing the memory bandwidth wall.
So perhaps it’s time to look at new alternatives. In fact, chipmakers are taking a hard look, or re-examining, one alternative—stacked 2.5D/3D c... » read more
