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

Manufacturing Bits: March 25


Proving the Big Bang theory A team of cosmologists using the BICEP2 telescope at the South Pole have discovered the first direct evidence of the Big Bang theory. The team includes Harvard University, the University of Minnesota, the California Institute of Technology/Jet Propulsion Laboratory, Stanford University/SLAC and others. Using the BICEP2, researchers found direct evidence of a cosm... » read more

Challenges Mount In Inspection And Metrology


Chipmakers are moving full speed ahead toward smaller process nodes, thereby driving up the costs and complexities in chip manufacturing. The migrations also are putting enormous stress on nearly all points of the fab flow, including a critical but unsung part of the business—process control. Process control involves 20 or so different segments in the inspection and metrology arena. Genera... » read more

Waiting For 3D Metrology


By Mark LaPedus Over the years, suppliers of metrology equipment have managed to meet the requirements for conventional planar chips. But tool vendors now find themselves behind in the emerging 3D chip era, prompting the urgent need for a new class of 3D metrology gear. 3D is a catch-all phrase that includes a range of new architectures, such as finFET transistors, 3D NAND and stacked-die ... » read more

Wanted: New Metrology Funding Models


By Mark LaPedus The shift toward the 20nm node and beyond will require new and major breakthroughs in chip manufacturing. Most of the attention centers around lithography, gate stacks, interconnects, strain engineering and design-for-manufacturing (DFM). Lost in the conversation are two other critical but overlooked pieces in the manufacturing puzzle—wafer inspection and metrology. ... » read more

Swimming In Data


By Ed Sperling So many warnings about data overload have been issued over the past decade that people generally have stopped paying attention to them. The numbers are so astronomical that increases tend to lose meaning. Nowhere is this more evident than in the semiconductor metrology world, where files are measured in gigabytes. And at each new process node, as the number of transistors a... » read more

Breakthroughs Required


Linear progressions have a hypnotic effect on even the smartest people. They lull everyone into thinking that progress—or at least a progression—is a straight line, with little or no recognition that things are changing around the edges. The periphery is definitely changing, though. And over the next couple of process nodes, the semiconductor manufacturing industry either will have to fi... » read more
