Directed Self-Assembly Gains Momentum


At last year’s SPIE Advanced Lithography symposium, directed self-assembly (DSA) grabbed the spotlight as chipmakers provided the first glimpse of their initial work and results with the technology. The results were stunning, thereby propelling DSA from a curiosity item to a possible patterning solution for next-generation devices. Last year, in fact, GlobalFoundries, IBM, Intel and Sams... » read more

EUV Reaches A Crossroads


[gettech id="31045" comment="EUV"] (EUV) [getkc id="80" comment="lithography"] is at a crossroads. 2014 represents a critical year for the technology. In fact, it may answer a pressing question about EUV: Does it work or not? It’s too early to make that determination right now, but there are more uncertainties than ever for the oft-delayed technology. Originally aimed for the 65nm node in... » read more

The Search For The Next Transistor


In the near term, the leading-edge chip roadmap looks fairly clear. Chips based on today’s finFETs and planar fully depleted silicon-on-insulator (FDSOI) technologies are expected to scale down to the 10nm node. But then, the CMOS roadmap becomes foggy at 7nm and beyond. The industry has been exploring a number of next-generation transistor candidates, but suddenly, a few technologies are ... » read more

Executive Insight: Luc Van den hove


Semiconductor Engineering sat down to discuss current and future process technology challenges with Luc Van den hove, president and chief executive of Imec. What follows are excerpts of that conversation. SE: The industry is simultaneously working on several new and expensive technologies. This includes extreme ultraviolet (EUV) lithography and the next-generation 450mm wafer size. The indu... » read more

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

Looking Beyond Moore’s Law


For decades, chip scaling has followed a simple linear curve. In this curve, the transistor gate-pitch scales at 0.7x every two years. This is the driving force behind Moore’s Law, which states that the number of transistors per chip roughly doubles every two years. But starting at the 16nm/14nm node, there is a change taking place in chip scaling. According to a chart from Imec, there are... » read more

The List Of Unknowns Grows After Silicon


As discussed earlier in this series, most proposed alternative channel schemes depend on germanium channels for pMOS transistors, and InGaAs channels for nMOS transistors. Of the two materials, InGaAs poses by far the more difficult integration challenges. Germanium has been present in advanced silicon CMOS fabs for several technology generations, having been introduced used in strained silicon... » read more

IMEC’s 30th Anniversary: A Consortium With Impact


In the history of semiconductor technology, one of the critical non-technology changes was the point when the biggest companies realized that they could not afford to do all the basic R&D. They agreed to collaborate in “pre-competitive” phase development through consortia such as IMEC and Sematech. IMEC is celebrating its 30th anniversary, and it’s interesting to recognize the signifi... » read more

Week In Review: Manufacturing, Design, Test


The technology of 3D "bioprinting" (the medical application of 3D printing to produce living tissue and organs) is advancing so quickly that it will spark a major ethical debate on its use by 2016, according to Gartner. At the same time, 3D printing of non-living medical devices such as prosthetic limbs, combined with a burgeoning population and insufficient levels of healthcare in emerging mar... » read more
