Keeping Up Power And Performance With Cobalt


Chip designers require simultaneous improvements in “PPAC”: power, performance and area/cost (Fig. 1). Achieving these improvements is becoming increasingly difficult as classic Moore's Law scaling slows. What's needed is a new playbook for the industry consisting of new materials, new architectures, new 3D structures within the chip, new methods to shrink feature geometries, and advanced p... » read more

Making Interconnects Faster


In integrated circuits, interconnect resistance is a combination of wire and via resistance. Wire resistance of a conductor depends on several factors, one of which is the electron scattering at various surfaces and grain boundaries. Via resistance, on the other hand, is a function of the thickness or resistivity of the layers at the bottom of the via through which current must travel. T... » read more
