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

Debate Heats Up Over Bigger Glass


For more than two decades, photomask makers have been talking about moving to a new and larger mask size, sometimes called “bigger glass” by the industry. Generally, the discussions about “bigger glass” have been all talk and no action. But now, some chipmakers are turning up the volume in the discussions and are pushing for a larger mask size. A larger mask size would require the ph... » read more

Executive Briefing: Getting Direct On Litho


Semiconductor Engineering sat down and talked with David Lam, principal of the David Lam Group, an investment and advisory firm. Lam is also the chairman of Multibeam, a multi-beam equipment startup for direct-write lithography and other applications. He founded Lam Research in 1980 and left as an employee in 1985. He served on Lam Research’s board for five years after that. SE: Multibeam ... » read more

Challenges Mount For EUV Masks


ASML Holding’s first production-worthy scanners for extreme ultraviolet (EUV) lithography are expected to ship this year, but there are still a number of challenges to bring the technology into high-volume manufacturing. As before, the three main challenges for EUV are the power sources, resists and photomasks. To date, the resists are making progress, while the EUV power sources remain a ... » read more

The Brave New World Of FinFETs


SoCs using 16nm and 14nm finFETs are expected to begin rolling out next year using a 20nm back-end-of-line process. While the initial performance and power numbers are looking very promising, the challenges of designing and building these complex chips are daunting—and there are more problems on the way. First, the good news. Initial results from foundries show a 150% improvement in perfor... » read more

Why does EUV matter?


By Brian Bailey The end of Moore’s Law has been predicted for almost as long as the law has existed. It normally comes down to some great technological barrier that cannot be breached, only to find that a solution is just around the corner and the concerns fade until the next barrier is identified. At DAC this year (2013), there were many predictions about why Moore’s Law will end in th... » read more
