FinFETs Give Way To Gate-All-Around


When they were first commercialized at the 22 nm node, finFETs represented a revolutionary change to the way we build transistors, the tiny switches in the “brains” of a chip. As compared to prior planar transistors, the fin, contacted on three sides by the gate, provides much better control of the channel formed within the fin. But, finFETs are already reaching the end of their utility as... » read more

Gaps In Metrology Could Impact Yield


For some time, chipmakers have been developing new and complex chip architectures, such as 3D NAND, finFETs and stacked die. But manufacturing these types of chips is no simple task. It requires a robust fab flow to enable new IC designs with good yields. In fact, yield is becoming a more critical part of the flow. Yield is a broad term that means different things to different parts of the ... » read more
