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

Optical Lithography, Take Two


By Mark LaPedus It’s the worst-kept secret in the industry. Extreme ultraviolet (EUV) lithography has missed the initial stages of the 10nm logic and 1xnm NAND flash nodes. Chipmakers hope to insert EUV by the latter stages of 10nm or by 7nm, but vendors are not counting on EUV in the near term and are preparing their back-up plans. Barring a breakthrough with EUV or other technology, IC ... » read more

Multicore Madness


By Mark LaPedus Smartphones and tablets are migrating towards new and faster application processors, basebands, graphics chips and memories. In the cell-phone chipset area alone, there are a multitude of options and design considerations. Some devices combine the application processor and modem on the same chip. Some are separate devices. In addition, the architectures range from single- to... » read more

Accelerating Moore’s Law


By Ed Sperling Ever since the inception of Moore’s Law, process nodes have moved forward at a rate of once every 18 to 24 months. Companies have been talking about slowing down the rate of progression as things get harder, but at least for the next couple of process nodes something very strange will occur—Moore’s Law will accelerate. The root cause is growing competition for a shrinki... » read more
