Argonne scientists create new oil-resistant filter technology

Argonne reports a novel new way to keep oil from clogging filters and equipment using ALD coated mabranes.

Crude oil is sticky stuff and often clogs filters membranes and other equipment used in the oil and gas industry. To address this problem, scientists at the U.S. Department of Energy’s (DOE) Argonne National Laboratory have developed a novel approach, which will prolong the lifetime of key industrial equipment.
The scientists used a method called atomic layer deposition, which uses chemical vapors to deposit a very thin coating of the metal oxide on all of the filter membrane surfaces. They experimented using different metal oxides on off-the-shelf commercial polymer membranes to find which ones worked the best. The team published the results in ACS Nano on August 14. 

This shows a membrane, when fouled by crude oil, but coated by titanium dioxide (TiO2), releases oil when placed in water.

Fabrication of buried nanostructures with flat surface by ALD

Fabrication of buried nanostructures by atomic layer deposition (Open Access)

Rizwan Ali, Muhammad Rizwan Saleem, Matthieu Roussey, Jari Turunen & Seppo Honkanen Scientific Reportsvolume 8, Article number: 15098 (2018) 

We present a method for fabricating buried nanostructures by growing a dielectric cover layer on a corrugated surface profile by atomic layer deposition of TiO2. Selecting appropriate process parameters, the conformal growth of TiO2 results in a smooth, nearly flat-top surface of the structure. Such a hard surface can be easily cleaned without damage, making the nanostructure reusable after contamination. The technique has wide applicability in resonance-domain diffractive optics and in realization of quasi-planar metamaterials. We discuss design issues of such optical elements and demonstrate the method by fabricating narrow-band spectral filters based on the guided-mode resonance effect. These elements have strong potential for, e.g., sensing applications in harsh conditions.

Drexel enables a Lithium-Sulfur battery evolution

Drexel’s College of Engineering reports that researchers and the industry are looking at Li-S batteries to eventually replace Li-ion batteries because a new chemistry that theoretically allows more energy to be packed into a single battery This improved capacity, on the order of 5-10 times that of Li-ion batteries, equates to a longer run time for batteries between charges.

However, the problem is that Li-S batteries have trouble maintaining their superiority beyond just a few recharge cycles. But a solution to that problem may have been found with new research.

The new approach, reported by in a recent edition of the American Chemical Society journal Applied Materials and Interfaces, shows that it can hold polysulfides in place, maintaining the battery’s impressive stamina, while reducing the overall weight and the time required to produce them.

Lithium-sulfur batteries could be the energy storage devices of the future, if they can get past a chemical phenomenon that reduces their endurance. Drexel researchers have reported a method for making a sulfur cathode that could preserve the batteries' exceptional performance. (Image from Drexel News)

Area-selective ALD using Si precursors as inhibitors

Area-Selective Atomic Layer Deposition Using Si Precursors as Inhibitors

Rizwan Khan, Bonggeun Shong, Byeong Guk Ko, Jae Kwang Lee, Hyunsoo Lee, Jeong Young Park, Il-Kwon Oh, Shimeles Shumi Raya, Hyun Min Hong, Kwun-Bum Chung, Erik J. Luber, Yoon-Seok Kim, Chul-Ho Lee, Woo-Hee Kim, and Han-Bo-Ram Lee

Chem. Mater., Article ASAP
DOI: 10.1021/acs.chemmater.8b02774

Short-chain aminosilanes, namely, bis(N,N-dimethylamino)dimethylsilane (DMADMS) and (N,N-dimethylamino)trimethylsilane (DMATMS), have been used as Si precursors for atomic layer deposition (ALD) of SiO2. In this work, the DMADMS and DMATMS Si precursors are utilized as inhibitors for area-selective ALD (AS-ALD). The inhibitors selectively adsorb on a SiO2 surface but not on H–Si, so that SiO2 becomes selectively deactivated toward subsequent ALD. The deactivation of the SiO2 surface by the inhibitors was investigated using various experimental and theoretical methods, including surface potential measurements, spectroscopic ellipsometry, and X-ray photoelectron spectroscopy. Better inhibition was observed for ALD of Ru and Pt than for ALD of Al2O3 and HfO2. Through quantum mechanical and stochastic simulations, the difference in the blocking ability for noble metal and metal oxide ALD by the aminosilane inhibitors could be attributed to the inherently partial surface coverage by the inhibitors at their saturation and the reactivity of the subsequent ALD precursors. As silane inhibitors can be easily integrated with vacuum-based processes to facilitate high volume manufacturing of upcoming electronic devices, the current study provides a potential approach for the utilization of AS-ALD in pattern fabrication inside 3D nanostructures.

NCD contracted to supply new ALD equipment for production of µ-OLED with LG Display

Korean ALD equipment manufacturer, NCD reports new order of µ-OLED ALD equipment from LG Display

"NCD has recently contracted with LGD to supply µ-OLED manufacture equipment which is new Lucida GuD Series for Al2O3-ALD encapsulation to avoid OLED degradation induced water and oxygen. Newly introduced Lucida GuD is high volume batch-type ALD equipment based on the process and hardware of OLED encapsulation technology of Lucida GD Series.

µ-OLED produced by this system is micro display with high resolution for augmented reality(AR) and virtual reality(VR) and has been expected the huge application and market in the future.

Otherwise, manufacture of µ-OLED requests high productivity like display industry therefore ALD tools with high film quality and low throughput for Semiconductor couldn’t meet the need of the customers and the market. So NCD is more expecting that this µ-OLED is next growth engine market because it has high volume ALD equipment and excellent OLED encapsulation technology.

NCD will lead µ-OLED ALD equipment market with this starting point and continue to make efforts to become the world’s best specialized ALD technology company.”

Patterned films by atomic layer deposition using Parafilm as a mask

Recently I have worked a lot with etch people. These guys are definitely a completely different breed from us ALD people. and I have gotten a bit annoyed of their obsession in using Capton Tape all the time. It is rather annoying to cut perfect pieces and then try to separate the protective film on the double sided sticky tape and then it is alos very tedious to clean up after you exposed it to a plasma with nasty gases. Now there is an alternative worth testing also for etch process development!  And for sure - ALD guys are behind it once again saving the etchers and Litho people like we did for multiple patterning.
Here is a very practical and low cost method for all of you who have the need to depositing patterned films by ALD or protect the substrate or certain areas from ALD film growth like the back side or edge. Zhang et al for University of Helsinki has investigated using Parafilm as a mask to block the film growth on selected areas of the substrate surface. Interestingly it works also well above the melting temperature of Parafilm (60 °C) since parfin in this form is very viscous up to the range 275 to 300 °C, below which quite many ALD processes produce high quality films.

A box of parafilm (From Wikimedia Commons, the free media repository)
On an interesting side note, the researchers from Helsinki has actually an Ir-ALD based device on board of the Mercury space ship BepiColombo heading towards the planet as we speak. According to Prof. Ritala [LINK] it is a ALD-Ir coated microchannel plate for x-ray focusing. However if this device had any Parafilm patterning involved in the making I do not know. Anyway in about 7 years we all look forward to see some results from the Satellite using high class Ir-ALD from Helsinki.
The study concludes:
  • The use of Parafilm as a blocking mask is a simple, clean and effective method for ALD film patterning.
  • The blocking ability was tested for ALD of Al2O3, TiO2 and Ir.
  • The Parafilm method works up to 275 °C but above 300°C the melted film will flow on vertical samples
  • Outgasing from the Parafilm at elevated temperatures may hinder growth around the edge of the Parafilm (observed for TiO2 and Ir ALD).
  • Potential use of the method besides R&D is seen for protecting contact areas in IC and MEMS

Patterned films by atomic layer deposition using Parafilm as a mask

Zhang, Chao ; Kalliomäki, Jesse ; Leskelä, Markku ; Ritala, Mikko
Journal of Vacuum Science & Technology A: Vacuum, Surfaces, and Films, January 2018, Vol.36(1)

This paper presents a new method for depositing patterned films by atomic layer deposition (ALD) using Parafilm as a mask to block the film growth on selected areas of the substrate surface. This offers an easy and efficient method for large area patterning from the millimeter to even meter scale as needed, for example, for protecting contact areas in integrated circuits and microelectromechanical system devices and in preventing film growth on the backside of substrates. It is shown here that Parafilm can protect the substrate against Al2O3, TiO2, and Ir film growth effectively. However, outgassing from the Parafilm affects the film growth on the unmasked areas differently for the three materials. For Al2O3, there are no significant effects on the growth rate and film quality on the nonmasked areas and the thickness profiles next to the Parafilm masked areas are narrow. For TiO2 and Ir, by contrast, the thickness profiles are wider and outgassing also slows down the Ir growth. Energy dispersive x-ray analysis confirms that Ir does not grow on Parafilm. Al2O3 and TiO2 films do grow on Parafilm, but after the ALD process, the Parafilm can be peeled off easily with tweezers and the areas under the Parafilm mask are without any deposition.
