FinFET Isolation: Bulk vs. SOI


Terry Hook of IBM recently contributed an article to ASN about FinFET isolation issues on bulk vs. SOI.  It generated immense interest, and created lots of discussion on various LinkedIn groups.  In case you missed it, here it is again. (This article is based on an in-depth presentation Terry gave at the SOI Consortium's Fully-Depleted Tech Workshop, held during VLSI-TSA in Taiwan, April 2... » read more

The Power Problem


For the past few years, EDA companies have been warning chipmakers that power will become the biggest issue they face at future nodes. They were right. While it may not be the only big problem—after all, the number of issues at each new tick of Moore’s Law is growing—power is certainly one of the most challenging and by far the most pervasive. In fact, the warnings about just how perni... » read more

Design-For-DSA Industry Begins To Assemble


By Mark LaPedus The industry is aggressively pursuing directed self-assembly (DSA) as an alternative patterning technology for future chip designs. DSA, which enables fine pitches through the use of block copolymers, is in the R&D pilot line stage today. The fab tools, process flows and materials are basically ready, but there are still several challenges to bring the technology from th... » read more

Foundry Models In Transition


By Jeff Chappell There may have been a time when AMD founder Jerry Sanders famous quote: "real men (i.e., real companies) have their own fabs” rang true, but in today's business climate it seems quaint at best. Fabless or fab-lite business models are more popular than ever today, while some IDMs have turned back the clock, so to speak, looking to improve capacity utilization and revenues ... » read more

Supply Chain Catch-Up


There always will be a few big companies marching to the latest process node available to them. The problem these days isn’t their commitment to pushing forward. It’s the baggage train following them. It’s getting longer, more diverse, and in some cases, it’s falling out of sync. The foundries are out in front with 14nm finFETs, and they’re already working on 10nm transistors—pos... » read more

Uncertainty Ahead


If finFETs work as planned, it’s likely they will show up in every complex SoC for decades to come. Adding another dimension to transistors has enormous potential at advanced nodes, and maybe even at older nodes. 3D transistors also could be part of stacked die, and they can be combined with fully depleted SOI—two other options for reducing power. Moreover, it’s likely that whatever G... » read more

x86 Processor Road Map No Longer Just About Speed


By Ed Sperling The decades-old approach of powerful processors with ever-faster clock speeds is changing. Performance matters in some settings, but the real concern is adding more functionality within power budgets. The most pressing tradeoff is now performance vs. power, which has forced processor architects at AMD, Intel and IBM to take into account everything from application software to... » read more

Directed Self-Assembly Grows Up


By Mark LaPedus At last year’s SPIE Advanced Lithography conference, Christopher Bencher, a member of the technical staff at Applied Materials, said the buzz surrounding directed self-assembly (DSA) technology resembled the fervor generated at the famous Woodstock rock concert in 1969. This was clearly evident from the tumultuous and free-flowing movement that threatened the status quo o... » read more

Swimming In Data


By Ed Sperling So many warnings about data overload have been issued over the past decade that people generally have stopped paying attention to them. The numbers are so astronomical that increases tend to lose meaning. Nowhere is this more evident than in the semiconductor metrology world, where files are measured in gigabytes. And at each new process node, as the number of transistors a... » read more

Getting Ready For High-Mobility FinFETs


By Mark LaPedus The IC industry entered the finFET era in 2011, when Intel leapfrogged the competition and rolled out the newfangled transistor technology at the 22nm node. Intel hopes to ramp up its second-generation finFET devices at 14nm by year’s end, with plans to debut its 11nm technology by 2015. Hoping to close the gap with Intel, silicon foundries are accelerating their efforts t... » read more
