Yole Développment is releaseing the Emerging Non-Volatile Memory 2017 June 28

Yole Développment: The key emerging non-volatile technologies like phase-change memory (PCM), magnetoresistive random access memory (MRAM) and resistive random access memory (RRAM) have long development histories. Yet, their adoption remains restricted to niche markets due to various factors. Available products have limited density, and the introduction of high density products by emerging NVM pioneers has been delayed. There are manufacturing challenges due to the introduction of new materials and process steps. Meanwhile, mainstream memory technologies are continuously improving in terms of density and cost. Finally, there has been an absence of a killer application that would challenge dynamic random access memory (DRAM) and NAND flash memory. [read further, LINK] - Thanks to Terry Francis for sharing this one!

 Time to market for differen memory technologies  (Yole Développment, LINK)

Unfortunately, Yole does not mention here the developments in Ferroelectric hafnium oxide based FeFET and FRAM (by NaMLab, Fraunhofer and Globalfoundries). There has been quite some progress over a 10 years development (originally imitated and discovered by Qimonda R.I.P.) so far and most recent approach by Imec integrating Ferro FETs in a bit scalable 3D-NAND style architecture. The main advantage of this technology is that in the case of a logic embedded memory cell and a stand alone 3D-NAND style version standard equipment and process flows can be used in HVM. In addition, according to Imec memory Guru Jan van Houdt, "It [FeFETs] has particularly interesting characteristics for future storage-class memory, which will help overcome the current bottleneck caused by the differences in speed between fast processors and slower mass memory"

The last couple of years there is an increased IP filing in hafnium oxide and related technologies and precursors and especially for ferroelectric memory. It was also apparent by studying the last VLSI program that there are man more mature activities in this technology and if I remember correctly there was 6-8 presentations on this topic. Possibly the report itself gives some insights also to the status of ferroelectric NVM technologies.

Imec is confident that their FeFET concept has all the required characteristics for both stand-alone and embedded memories, from non-volatile DRAM to Flash-like memories. (2017 Symposia on VLSI Technology and Circuits, Kyoto Japan June 7, 2017, source

Leading edge ALD is a technology enabler for trailing edge

According to a recent article in Semiconductor Engineering on the reworking of established nodes (May 24th, 2017 - By: Ed Sperling, LINK) the benefits of device scaling don’t apply equally to all markets. However, the process technology does. A good example of this is, according to my opinion, is ALD high-k (Al2O2, ZrO2, HfO2, Ta2O5 etc.) MIM Caps that have multiple HVM applications in 200mm fabs around the world. As well as ALD liners and etch stops in MEMS and LED production.

According to Ed Sperling, that " .. is why the foundries, equipment makers and packaging houses have introduced a menu of possible options at established nodes, including new materials as well as new process options, including low-power, ultra-low power, high-performance and low-cost options at the same nodes."

Interestingly this also applies to ALD for high volume manufacturing and in an interview with ASM Peter Zagvijn, senior technical product manager a message was given:

“By using thin films on 200mm you can get higher function but still have low cost. This is a technology enabler. It will be important for high-voltage electronics and electric cars because it allows you to extend the platform maintainability and the lifetime of the equipment by transferring what happens at the leading edge to the lagging edge. Using ALD technology, there are more than 50 films available for diffusion on one platform.”

In addition, Zagvijn said that ALD technology and capability will be important in wafer-level packaging.

Light, Superelastic, Electrically Conductive, and Flame-Retardant Graphene / ALD Ceramic Metamaterial

Researcher from Lanzhou University (China) and Purdue University (USA) has developed a new ceramic/graphene wonder metamaterial (GCM) with microstructure-derived superelasticity and structural robustness is achieved by designing hierarchical honeycomb microstructures

The GCM is composited by two brittle constituents (graphene and ceramic) assembled in multi-nanolayer cellular walls. The GCM demonstrates a sequence of multifunctional properties simultaneously that have not been reported for ceramics and ceramics–matrix–composite structures, such as: 
  • flyweight density
  • 80% reversible compressibility
  • high fatigue resistance
  • high electrical conductivity
  • excellent thermal-insulation/flame-retardant performance simultaneously. 

All details can be find in the Advanced Materials publication below. According to the suppoirting information the Al2O3 ceramic depositions were performed in an Utratech Fiji F200 ALD system (pictured above) at 250 C using trimethylaluminum (TMA) and H2O as the aluminum and oxygen source, respectively.

Beneq in 2016 – A Successful Strategic Transformation

Beneq’s financial figures from 2016 show growth, encouraging signs of transformation, and positive development in industrial ALD solutions. Beneq corporation turnover grew to 22,2 million euros in 2016. And Beneq is a truly global company: 98% of the company turnover came from outside Finland.

The year 2016 was a transformation year for Beneq in many ways. In Thin Film Solutions, there was a shift from traditional ALD research equipment towards large-scale industrial ALD equipment and thin film services – a trend which has continued during 2017. The equipment business order flow in the first quarter of 2017 was 70% higher than during Q1/2016 with several new industrial ALD customers and repeat orders from customers who are expanding ALD-based industrial production.
For the Thin Film Solutions business unit, major development areas are industrial ALD equipment and continuous large-area ALD processes based on Beneq’s pioneering Spatial ALD technology, which allows fast low-cost processing of materials in industries that require extremely precise coatings and high capacity, such as OLED and flexible electronics markets.

New prospects for universal memory from MIPT Russia using Picosun ALD

MIPT Reports: Researchers from MIPT’s Center of Shared Research Facilities have found a way to control oxygen concentration in tantalum oxide films produced by atomic layer deposition. These thin films could be the basis for creating new forms of nonvolatile memory.

The MIPT non-volatile ReRAM memory cell is based on ALD deposited tantalum oxide using tantalum ethoxide and water.

“The hardest part in depositing oxygen-deficient films was finding the right reactants that would make it possible to both eliminate the ligands contained in the metallic precursor and control oxygen content in the resulting coating,” says Andrey Markeev, who holds a PhD in physics and mathematics and is a leading researcher at MIPT. “We achieved this by using a tantalum precursor, which by itself contains oxygen, and a reactant in the form of plasma-activated hydrogen.”

Atomic Layer Deposition for Coating of Complex 3D Optics by LASEROPTIK

Here is a great overview on ALD for coating complex 3D compnents for optics from LASEROPTIK, Germany (LINK).

Laseroptik offers ALD coatings ranging from UV to IR.

Atomic Layer Deposition for Coating of Complex 3D Optics - From theory to practice 

Abstract: Atomic Layer Deposition (ALD) is a chemical vapor coating technique that has recently been adapted for precision laser optics to perform highly conformal multilayer coatings on complex 3D substrates like hemispheres, axicons or multi-sided prisms. In our brief report, we explain some ALD fundamentals and describe the way from idea and single-layer films to simple AR (anti-reflection) coatings and even more ambitious designs, like non-polarizing beam splitters, performed on complex optical substrates.

The article contains a new nice graphical representation of CVD vs. ALD process description that I have not seen before - reminds me of winter vs an April typ of weather changing all thee time between winter and summer, rain, snow and sunshine.


LASEROPTIK is a German manufacturer of high power laser optics and coatings from VUV to IR, using PVD methods like e-beam evaporation, ion assisted deposition, magnetron sputtering, ion beam sputtering and recently the chemical vapor method of atomic layer deposition. LASEROPTIK runs more than thirty coating machines  and processes about 150,000 optics per year, from needle head size to laser mirrors of up to two meters in length. The company was founded in 1984 by Dr. Johannes Ebert as a spin-off from Hanover University. Main customers are laser manufacturers from industry, medicine and scientific research.
