Here Comes 7nm


A consortium of companies involving IBM, GlobalFoundries and Samsung has rolled out the first 7nm test chip using silicon germanium as a substrate, using EUV to pattern multiple layers. While this doesn't mean the cost equation is even close to being solved, or that more than a handful of companies will push forward to that node anytime soon using SiGe as the substrate material, it does cre... » read more

Litho Challenges Break The Design-Process Wall


The days when chip designers could throw tape “over the wall” to the manufacturing side are long gone. Over the last several technology generations, increasingly restrictive process kits have forced designers to accommodate their circuit structures to the manufacturing process. Lacking a successor to 193nm lithography, the industry has turned to increasingly complex resolution enhancemen... » read more

Is EUV Making Progress?


By Ann Steffora Mutschler & Ed Sperling EUV has been promised for a couple of decades, counted on for at least three process nodes on the ITRS roadmap, and considered essential to chip manufacturing since 22nm. Billions of dollars have been invested in R&D, engineering teams from around the world have contributed to its development, and still serious problems persist. Just how close... » read more

Not All Scientific Problems Can Be Solved


In the early part of the 20th century psychologist Karl Lashley set out to locate and study the engram, the memory storage center for the human brain. He never found it. In fact, he ended up disproving the theory that an engram even exists, which was far more important to the understanding of the brain than if he had proven the existence of an engram. The results of more than six decades of ... » read more

Speeding Up E-beam Inspection


Wafer inspection, the science of finding killer defects in chips, is reaching a critical juncture. Optical inspection, the workhorse technology in the fab, is being stretched to the limit at advanced nodes. And e-beam inspection can find tiny defects, but it remains slow in terms of throughput. So to fill the gap, the industry has been working on a new class of multiple beam e-beam inspectio... » read more

SoC Integration Headaches Grow


As the number of IP blocks grows, so do the headaches of integrating the various pieces and making sure they perform as planned within a prescribed power envelope. This is easier said than done, particularly at the most advanced process nodes. There are more blocks, more power domains, more states and use-model dependencies, and there is much more contention for memories. There are physical ... » read more

Manufacturing Bits: June 16


Harmonic EUV The U.S. Department of Energy’s Lawrence Berkeley National Laboratory has devised an efficient extreme ultraviolet (EUV) source. The technology could one day be used for a new class of metrology tools, based on angle-resolved photoemission spectroscopy (ARPES). This technique makes use of a photoelectric effect for studying materials. To enable the source, Berkeley Labs devel... » read more

The Week In Review: Manufacturing


Christopher Rolland, an analyst at FBR, made a startling statement in a recent report. “At the pace of consolidation set thus far this year, 32% of all U.S. publicly traded semiconductor companies would be acquired in 2015! While this run-rate is not likely sustainable and should slow as the year progresses, we still expect ~15% consolidation rates for the remainder of this cycle (above low-t... » read more

What’s Different At 16/14nm?


Will finFETs live up to their promise? It depends on whom you ask, when you ask that question, and the intended application of a design. But across the semiconductor industry, there is general agreement that it's getting easier to work at the most advanced nodes as tools and flows are better understood and overall experience increases. There is no question that [getkc id="185" kc_name="finFE... » read more

Manufacturing Bits: May 26


Table-top EUV Swinburne University of Technology has developed a table-top extreme ultraviolet (EUV) laser power source. The source could be used to develop a system for use in metrology and other applications. The table-top setup is a new way to generate bright beams of coherent EUV radiation. It may offer a cost-effective alternative to large-scale facilities, such as synchrotrons or free... » read more
