Interconnect Challenges Grow


Qualcomm outlined the technology challenges facing mobile chip suppliers at a recent event. In no particular order, the challenges include the usual suspects—area scaling, power reduction, performance and cost. Another concern for Qualcomm is an often-overlooked part of the equation—the backend-of-the-line (BEOL). In chip production, the BEOL is where the interconnects are formed within ... » read more

Why Would IBM Sell Its Semi Group?


Rumors are always just rumors until proven otherwise in business, but in the case of IBM’s semiconductor business, hints about the sale of its semiconductor business are particularly noteworthy. Much has changed since the days when IBM—as International Business Machines—went head-to-head with AT&T’s quasi-public Bell Labs and Xerox’s Palo Alto Research Center (PARC). The breakup of... » read more

Waiting For Next-Generation Lithography


Nearly 30 years ago, optical lithography was supposed to hit the wall at the magical 1 micron barrier, prompting the need for a new patterning technology such as direct-write electron beam and X-ray lithography. At that time, however, the industry was able to push optical lithography for volume chip production at the 1-micron node and beyond. This, in turn, effectively killed direct-write e-... » read more

Fab Tool Industry Has Lost Its Way


The relationship between chipmakers and fab tool vendors has always been a bit rocky, but the supply chain has generally worked. Chipmakers demand a tool for a particular application. Then, tool makers attempt to deliver the goods, and ask few, if any, questions. Now, fab tool executives are beginning to ask some tough questions about the industry. And the tension is mounting between equ... » read more

Mixed Signals Seen For Fab Tool Industry


After a slight downturn in 2013, the semiconductor equipment market is expected to rebound and see solid growth in 2014, according to forecasters at SEMI’s Industry Strategy Symposium (ISS) at Half Moon Bay, Calif. Gartner, IC Insights and VLSI Research separately projected strong growth in the fab tool industry in 2014. But on the downside, the number of large fab tool buyers continues to... » read more

DSA, Multi-beam Make Steady Progress


Semiconductor Engineering sat down to discuss current and future lithography challenges with Laurent Pain, lithography lab manager at CEA-Leti. What follows are excerpts of that conversation. SE: CEA-Leti has two major programs in lithography. One is in directed self-assembly (DSA) and the other is in multi-beam e-beam. Let’s start with multi-beam. What is Leti doing in multi-beam and what... » read more

What’s After 10nm?


For some time, chipmakers have roughly doubled the transistor count at each node, while simultaneously cutting the cost by around 29%. IC scaling, in turn, enables faster and lower cost chips, which ultimately translates into cheaper electronic products with more functions. Consumers have grown accustomed to the benefits of Moore’s Law, but the question is for how much longer? Chips based ... » read more

Momentum Builds For Monolithic 3D ICs


The 2.5D/3D chip market is heating up on several fronts. On one front, stacked-die using through-silicon vias (TSVs) is taking root. In a separate area, Samsung is sampling the world’s first 3D NAND device, with Micron and SK Hynix expected to follow suit. And now, there is another technology generating steam—monolithic 3D integrated circuits. In stacked-die, bare die are connected using... » read more

The Week In Review: Oct. 18


By Mark LaPedus & Ed Sperling The problems continue with extreme ultraviolet (EUV) lithography. ASML promised to deliver an 80 Watt power source by year’s end. Now, the company said it only will have a 70 Watt source by mid-2014. “We are focusing on reaching the 70 Watts by the middle of next year,” said Peter Wennink, ASML’s CEO, in a conference call to discuss the company’s res... » read more

Multi-Beam Begins To Shine


After years of R&D and promises, multi-beam electron-beam technology is delayed and late to the market. The technology requires more funding and work than previously thought. And generally, the skepticism is running high for the technology. Finally, however, there is a ray of hope, and some momentum, in multi-beam—at least on the photomask front. Seeking to accelerate its multi-beam te... » read more
