Improving Yield Of 2.5D Designs


While progress is being made on the packaging side of 2.5D design, more needs to be resolved when it comes to improving yields. Proponents of 2.5D present compelling benefits. Arif Rahman, a product architect at Altera, noted that the industry trend of silicon convergence is leading to multiple technologies being integrated into single-chip solutions. “2.5D/3D integration has multiple adva... » read more

What If EUV Fails?


It’s the worst kept secret in the industry, but extreme ultraviolet (EUV) lithography will likely miss the 10nm node. So, chipmakers will likely extend and use today’s 193nm immersion lithography down to 10nm. This, of course, will require a complex and expensive multiple patterning scheme. Now, chipmakers are formulating their lithography strategies for 7nm and beyond. As it stands now,... » read more

Billions And Billions Invested


Over the years, next-generation [getkc id="80" kc_name="lithography"] (NGL) has suffered various setbacks and delays. But until recently, the industry basically shrugged its shoulders and expressed relatively little anxiety about the NGL delays. After all, optical lithography was doing the job in the fab and NGL would eventually materialize. Today, however, the mood is different. In fact, th... » read more

Time To Revisit 2.5D And 3D


Chipmakers are reaching various and challenging inflection points. In logic, many IC makers face a daunting transition from planar transistors at 20nm to finFETs at 14nm. And on another front, the industry is nearing the memory bandwidth wall. So perhaps it’s time to look at new alternatives. In fact, chipmakers are taking a hard look, or re-examining, one alternative—stacked 2.5D/3D chi... » read more

Favorite Forecast Fallacies


It’s difficult to make predictions, especially about the future. – An Old Danish Proverb. The GSA Silicon Summit was held on Thursday, April 10th at the Computer History Museum in Mountain View, CA. The opening panel session was entitled Advancements in Nanoscale Processing. The panelists were Rob Aitken (ARM), Adam Brand (Applied Materials), Peter Huang (TSMC), Nick Kepler (VLSI Researc... » read more

Power Moves Up To First Place


Virtually every presentation delivered about semiconductor design or manufacturing these days—and every end product specification that uses advanced technology—incorporates some reference to power and/or energy. It has emerged as the most persistent, most problematic, and certainly the most talked about issue from conception to marketplace adoption. And the conversation only grows louder... » read more

How Much Will That Chip Cost?


From the most advanced process nodes to the trailing edge of design there is talk about the skyrocketing cost of developing increasingly complex SoCs. At 16/14nm it’s a combination of multi-patterning, multiple power domains and factoring in physical and proximity effects. At older nodes, it’s the shift to more sophisticated versions of the processes and new tools to work within those proce... » read more

Blog Review: March 26


Synopsys’ Eric Huang has discovered a video of Superman using a GoPro camera (scroll down to bottom of page). So this is what it’s like to stop bullets with your hand. Cadence’s Tom Hackett zeroes in on mobile interfaces in a video—SoC fabric, memory and chip-to-chip. Nice whiteboard drawing. Mentor’s Anil Khanna looks at a methodology for developing high-performance embedded so... » read more

Litho Is Out Of Sync


EUV’s repeated missed deadlines, and the slow-motion response by the rest of the industry to fill the void with alternatives, is having ripple effects in every facet and corner of the semiconductor industry. It’s making design harder and more expensive, introducing potential errors into the DFM flow, and greatly increasing the amount of time it takes to process wafers. It’s also adding a ... » read more

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
