ALD Tungsten Solves Capacity Challenges in 3D NAND Device Manufacturing


Our increasingly connected and ever “smarter” world generates increasing amounts of data, putting pressure on manufacturers who face new technical challenges in delivering the increasing capacity required for processing and storage. The ALD Tungsten process is helping 3D NAND manufacturers overcome the technical challenges of producing memory chips with higher storage capacity. 3D NAND a... » read more

3D NAND Metrology Challenges Growing


3D NAND vendors face several challenges to scale their devices to the next level, but one manufacturing technology stands out as much more difficult at each turn—metrology. Metrology, the art of measuring and characterizing structures, is used to pinpoint problems and ensure yields for all chip types. In the case of 3D NAND, the metrology tools are becoming more expensive at each iteration... » read more

Innovative Solutions To Increase 3D NAND Flash Memory Density


In the last 10 years, 3D NAND flash memory has enabled a new generation of non-volatile solid-state storage useful in nearly every electronic device imaginable. 3D NAND can achieve data densities exceeding those of 2D NAND structures, due to the relative ease of 3D integration, even when fabricated on later generation technology nodes. 3D NAND structures contain vertical channels which orthogo... » read more

5 Top Storylines For NAND Biz


2019 is expected to be a busy, if not difficult, year in the NAND flash memory market. Vendors will continue to ramp up 3D NAND, the successor to traditional 2D or planar NAND. Then, over the last year, prices for NAND have dropped with oversupply in the market. What’s in store in 2019? Vendors are expected to rush out their next-generation products. Then, there is a debate whether the... » read more

Creating Higher Density 3D NAND Structures


3D NAND flash memory has enabled a new generation of non-volatile solid-state storage useful in nearly every electronic device imaginable. 3D NAND can achieve data densities exceeding those of 2D NAND structures, even when fabricated on later generation technology nodes. The methods used to increase storage capacity come with potentially significant tradeoffs in memory storage, structural sta... » read more

Variation Issues Grow Wider And Deeper


Variation is becoming more problematic as chips become increasingly heterogeneous and as they are used in new applications and different locations, sparking concerns about how to solve these issues and what the full impact will be. In the past, variation in semiconductors was considered a foundry issue, typically at the most advanced process node, and largely ignored by most companies. New p... » read more

Top Stories For 2018


Each year, I look back to see what articles people like to read. The first thing that has amazed me each year at Semiconductor Engineering is that what should be a strong bias towards articles published early in the year never seems to play out. The same is true this year. More than half of the top articles were published after July. The second thing that remains constant is that people love... » read more

Fab Equipment Challenges For 2019


After a period of record growth, the semiconductor equipment industry is facing a slowdown in 2019, in addition to several technical challenges that still need to be resolved. Generally, the equipment industry saw enormous demand in 2017, and the momentum extended into the first part of 2018. But then the memory market began deteriorating in the middle of this year, causing both DRAM and NAND ... » read more

5 Observations From Intel’s Event


Not long ago, Intel hosted its “Architecture Day,” where top executives from the chip giant revealed the company’s latest products and next-generation technologies. The company also discussed its strategy. To be sure, it’s a critical time for Intel. In June, Brian Krzanich was forced out as chief executive and the company is still looking for a permanent CEO. Plus, Intel has delayed it... » read more

What’s Changing In Memory


As emerging big data and artificial intelligence (AI) applications, including machine learning, drive innovations across many industries, the issue of how to advance memory technologies to meet evolving computing requirements presents several challenges for the industry. The mainstream memory technologies, DRAM and NAND flash, have long been reliable industry workhorses, each optimized for s... » read more
