The Evolution Of EUV


EUV systems are beginning to ship to large foundries in volume, setting the stage for one of the biggest leaps in technology the semiconductor industry has ever witnessed. ASML has emerged as the sole supplier in this market, but it has taken an entire ecosystem to develop EUV. It has taken billions of dollars of investment by ASML, along with enormous cash infusions by Intel and TSMC, contr... » read more

Playing With Chip Volumes


The overall market for semiconductors continues to grow, but the number of applications that will generate enormous volumes continues to shrink. In theory, this is good for the overall semiconductor industry, but it raises important questions about where R&D dollars will go in the future. The fundamental problem is that the semiconductor business is a volume business for one or two markets. ... » read more

The Return Of Time Sharing


As early as the 1960s, it wasn't uncommon to hear that transistors would be free. Those were pretty bold statements at the time, considering most computers in those days cost $1 million, required special rooms, and budding computer scientists usually had to sign up to use mainframe computers for one-hour time slots—often in the middle of the night or on weekends. Still, those predictions ... » read more

Putting The Brakes On Consolidation


China's efforts to reduce its trade deficit by acquiring technology outside of its borders—particularly in the areas of process technology and memory—are hitting some snags. Any proposed acquisitions are being closely monitored by government agencies around the globe, and in many cases they have been quietly derailed. The Committee on Foreign Investment in the United States (CFIUS) is pa... » read more

Advanced Packaging Requires Better Yield


Whether Moore's Laws truly ends, or whether the semiconductor industry reaches into the Angstrom world after 3nm—the semiconductor industry dislikes fractions—advanced packaging increasingly will dominate semiconductor designs. Apple already is on board with its iPhone 7, using TSMC's fan-out approach. And all of the major foundries and OSATs are lining up with a long list of capabilitie... » read more

How Many Nanometers?


What’s the difference between a 10nm and a 7nm chip? That should be a straightforward question. Math, after all, is the only pure science. But as it turns out, the answer is hardly science—even if it is all about numbers. Put in perspective, at 65nm, companies defined the process node by the half pitch of the first metal layer. At 40/45nm, with the cost and difficulty of developing n... » read more

450mm And Other Emergency Measures


Talk about boosting wafer sizes from 300mm to 450mm has been creeping back into presentations and discussions at conferences over the past couple months. Earlier this year, discussions focused on panel-level packaging. These are basically similar approaches to the same problem, which is that wafers need to be larger to reap efficiencies out of device scaling. Whether either of these approach... » read more

Changing Economics In Chip Manufacturing


The foundry and equipment businesses are poised for significant changes that could affect the balance of power far beyond just the semiconductor manufacturing sector. It’s no secret that the number of companies developing new chips at 7nm is shrinking. There will be even fewer at 5nm. The business case for moving forward is that density must provide a competitive edge. But that density imp... » read more

Roots Of Distrust Spread


For most of the history of semiconductors there has been a persistent fear that someone would steal intellectual property from one company and sell it to another. There have been innumerable lawsuits involving corporate secrets that cross from one company to the next, and from one country to the next. The biggest concerns always were at the leading edges of technology, where those secrets w... » read more

The Road To 5nm


There is strong likelihood that enough companies will move to 7nm to warrant the investment. How many will move forward to 5nm is far less certain. Part of the reason for this uncertainty is big-company consolidation. There are simply fewer customers left who can afford to build chips at the most advanced nodes. Intel bought Altera. Avago bought Broadcom. NXP bought Freescale. GlobalFoundrie... » read more
