Gaps In Metrology Could Impact Yield


For some time, chipmakers have been developing new and complex chip architectures, such as 3D NAND, finFETs and stacked die. But manufacturing these types of chips is no simple task. It requires a robust fab flow to enable new IC designs with good yields. In fact, yield is becoming a more critical part of the flow. Yield is a broad term that means different things to different parts of the ... » 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

The Bumpy Road To 3D NAND


The NAND flash memory market is dynamic, but it’s also sometimes predictable. Suppliers tend to roll out identical NAND flash chips and then scale them to smaller geometries. And NAND chip prices rise and fall, depending on the supply/demand equation at a given point. Going forward, though, the NAND market is expected to become less predictable, if not chaotic, amid a new and major technol... » read more

The Road Ahead for 2014: Semiconductors


Last week, Semiconductor Engineering examined the 2014 predictions from several thought leaders in the industry and published those predictions that related to general market trends. Many of those predictions require some advances in semiconductor technologies and fabrications capabilities. It is those predictions that will be examined in this part, followed next week by the predictions related... » read more

2014 CapEx: Memory Is Leading The Way


The semiconductor industry is expensive. Billions of dollars are spent every year to keep the fabs running, build new fabs, and push the process technology to greater and greater heights. Billions more will be spent to make 450mm production a reality. In January 2013, Semico predicted that, based on initial indications from some companies, total CapEx would be flat this year. Based on current d... » read more

Challenges Mount In Inspection And Metrology


Chipmakers are moving full speed ahead toward smaller process nodes, thereby driving up the costs and complexities in chip manufacturing. The migrations also are putting enormous stress on nearly all points of the fab flow, including a critical but unsung part of the business—process control. Process control involves 20 or so different segments in the inspection and metrology arena. Genera... » read more

3D NAND Is A Reality – What’s Next?


One of the biggest developments taking place in the semiconductor industry is the emergence of 3D NAND memory technology. Products are available today that feature 3D NAND devices. It has taken years to become a reality — since Toshiba first discussed the concept of 3D NAND at the VLSI Symposium in 2007 – and now it is poised to replace planar NAND flash memory for storage. The path that... » read more

Applied-TEL Watch


By Mark LaPedus So far this year, the biggest story in the fab tool industry is fairly obvious—Applied Materials recently signed a definitive agreement to acquire rival Tokyo Electron Ltd. (TEL) for about $9.3 billion. The blockbuster announcement will likely be the top story of 2013. Of course, the integration of Applied and TEL will be a challenge. In any case, the Applied-TEL deal is i... » read more

What’s After 3D NAND?


By Mark LaPedus Planar NAND flash memory is on its last scaling legs, with 3D NAND set to become the successor to the ubiquitous 2D technology. Samsung Electronics, for one, already has begun shipping the industry’s first 3D NAND device, a 24-level, 128-gigabit chip. In addition, Micron and SK Hynix shortly will ship their respective 3D NAND devices. But the Toshiba-SanDisk duo are the lo... » read more

The Week In Review: Aug. 19


By Mark LaPedus Applied Materials named Gary Dickerson, who has been serving as president of the company, as CEO. Mike Splinter, who held the reins since 2003, was elevated to executive chairman of the board. Dickerson served as the CEO of Varian, which Applied acquired in 2011, as well as the president and COO of KLA-Tencor. Applied Materials also announced its Q3 results. The company rep... » read more
