IEDM 2019 News - Intel roadmap to 1.4 nm by 2029

Limitless - Intel disclosed its extended roadmap to 1.4 nm process node by 2029 including back porting: One of the interesting disclosures at the IEEE International Electron Devices Meeting (IEDM) was that Intel expects to be on 2 year cadence with its manufacturing process node technology, starting with 10nm in 2019 and moving to 7 nm EUV in 2021, then 5 nm in 2023, 3 nm in 2025, 2 nm in 2027, and 1.4 nm in 2029. 
 
In between each process node, as Intel has stated before, there will be iterative + and ++ versions of each in order to extract performance from each process node. The only exception to this is 10nm, which is already on 10+, so we will see 10++ and 10+++ in 2020 and 2021 respectively. The interesting element is the mention of back porting. This is the ability for a chip to be designed with one process node in mind, but perhaps due to delays, can be remade on an older ‘++’ version of a process node in the same timeframe.

 
Intel's slide with ASML's animations overlayed, as shown in the slide deck distributed by ASML. Note by Anandtech: "After some emailing back and forth, we can confirm that the slide that Intel's partner ASML presented at the IEDM conference is actually an altered version of what Intel presented for the September 2019 source. ASML added animations to the slide such that the bottom row of dates correspond to specific nodes, however at the time we didn't spot these animations (neither did it seem did the rest of the press). It should be noted that the correlation that ASML made to exact node names isn't so much a stretch of the imagination to piece together, however it has been requested that we also add the original Intel slide to provide context to what Intel is saying compared to what was presented by ASML. Some of the wording in the article has changed to reflect this. Our analysis is still relevant." Please see the full article in Anandtech for all the details: LINK

Imec shows excellent performance in ultra-scaled FETs with 2D-material channel

[Press release, imec, LINK] SAN FRANCISCO (USA), December 8, 2019 — At this year’s IEEE International Electron Devices Meeting (Dec 7-11 2019), imec, a world-leading research and innovation hub in nanoelectronics and digital technologies, reports an in-depth study of scaled transistors with MoS2 and demonstrates best device performance to date for such materials. 

TEM pictures showing (a) 3 monolayers MoS2 channel, with contact length 13nm and channel length 29nm Transfer characteristics have improved sub-threshold swing (SS) with thinner HfO2. (www.imec.be)

MoS2 is a 2D material, meaning that it can be grown in stable form with nearly atomic thickness and atomic precision. Imec synthesized the material down to monolayer (0.6nm thickness) and fabricated devices with scaled contact and channel length, as small as 13nm and 30nm respectively. These very scaled dimensions, combined with scaled gate oxide thickness and high K dielectric, have enabled the demonstration of some of the best device performances so far. Most importantly, these transistors enable a comprehensive study of fundamental device properties and calibration of TCAD models. The calibrated TCAD model is used to propose a realistic path for performance improvement. The results presented here confirm the potential of 2D-materials for extreme transistor scaling – benefiting both high-performance logic and memory applications.

High-performance lithium-ion battery materials with Picosun ALD

ESPOO, Finland, 3rd December 2019 – Picosun Group, the provider of AGILE ALD® (Atomic Layer Deposition) thin film coating technology for global industries, reports excellent results achieved with ALD in the manufacturing of lithium ionthin film battery materials.

Solid-state Li-ion thin film batteries (SSLIBs) are small, compact and may have flexible construction. They don’t contain any aggressive liquid substances, so they are safe to use. Furthermore, SSLIBs possess excellent energy storage capacity, which is why they are regarded as ideal power sources for electric cars, laptops, tablets and smartphones, wireless sensors, implantable and wearable medical devices, and harvesting devices for renewable energy sources. The impact of Li-ion battery technology on our modern society, permeated by portable electronics, wireless data transfer and mobile communications, is so huge that it earned its developers, Dr. John B. Goodenough, Dr. M. Stanley Whittingham, and Dr. Akira Yoshino, the Nobel chemistry prize this year.

As the performance requirements of these devices increase, functional characteristics of their power sources should be improved as well. Transition from planar, 2D battery geometry to corrugated 3D one with much higher active surface area for energy storage could augment the energy and power density of SSLIB. However, finding a suitable method for depositing the functional material layers on the complex microscale structures of the 3D batteries poses another challenge.

Image source: Yue et. al., Fabrication of Si-based three-dimensional microbatteries: A review, in Frontiers of Mechanical Engineering 2017 (doi: 10.1007/s11465-017-0462-x).

Picosun’s ALD technology has now been successfully used to fabricate high-quality, high-performance thin film NiO anodes for SSLIBs. Compared to graphite, which is widely used to produce anodes of lithium-ion batteries, deposited NiO films had more than twice as large capacity and more than three times as high density (*). The surpassing characteristics of NiO potentially allow improvement of the energy density of SSLIBs.

In addition to high quality and performance of the ALD NiO anodes, ALD’s unmatched capability to produce conformal and uniform coatings with excellent purity and repeatability inside challenging microscale architectures such as high aspect ratio trenches makes it an ideal method for 3D SSLIB materials manufacturing. Also, the ALD processes for several other anode materials such as SnO2, CoO, and MnO are well-known and thoroughly studied.

“We are very pleased with the PICOSUN® ALD system at our facilities, and all the support and consultancy we have received from Picosun over the years. With our ALD system we have been able to deposit dense, uniform ALD NiO films with low roughness and very high capacity. The excellent qualities of these films allowed us to develop high-performance anodes for SSLIBs,” says Picosun customer, Dr. Maxim Maximov from Peter the Great St.Petersburg Polytechnic University (SPbPU), Russia.

“Battery applications are yet one example of ALD’s flexibility as a method, and how new industries discover the possibilities of ALD day by day. Deep trenches with aspect ratios exceeding 1:2500 have been successfully coated with our ALD tools equipped with our patented Picoflow™ feature, which further advocates the use of our technology in 3D solid state Li-ion battery manufacturing. We are happy that our ALD solutions can be potentially utilized in future’s energy storage solutions in conjunction with clean energy production, and to power more compact healthcare devices, to improve people’s quality of life,” states Dr. Jani Kivioja, CTO of Picosun Group.

Picosun provides the most advanced ALD thin film coating technology to enable the industrial leap into the future, with turn-key production solutions and unmatched expertise in the field. Today, PICOSUN® ALD equipment are in daily manufacturing use in numerous major industries around the world. Picosun is based in Finland, with subsidiaries in Germany, North America, Singapore, Taiwan, China and Japan, offices in India and France, and a world-wide sales and support network.

PEALD processes employing Strem supplied TDMASn precursor presented by diverse groups of researchers

We offer prepackaged precursors in ALD Cylinders!


Atomic layer deposition (ALD) using Tin (Sn) based compounds have been widespread in applications, such as sensors, Li-ion batteries, catalysts, photovoltaics. Recently, researchers have reported state-of-the-art applications like 3D thin-film solid-state batteries (by Pearse et. al.) and efficient perovskite solar cells (by Guan et. al. and Sun et. al.). Many of these applications feature layers that are susceptible to degradation at elevated temperatures. It’s mandatory to deposit SnO2 below 200°C for applications such as perovskite and silicon heterojunction solar cells. Alternatively, plasma-enhanced atomic layer deposition (PEALD) with Strem Chemicals’ highly reactive metalorganic precursor, tetrakis(dimethylamino)tin (TDMASn), with a decomposition temperature range of 250–300°C, also enables low deposition temperatures. 


Figure 1. 50-1815 Structure


Strem Chemicals offers TDMASn [Sn[N(CH3)2]4] (catalog number 50-1815) precursor, which has been widely accepted in the PEALD community worldwide for the deposition of tin-based compounds. The colorless to pale yellow liquid phase precursor with a density of 1.169 at 20°C and vapor pressure of 15 Torr is sold pre-packed, in an ALD cylinder by Strem Chemicals (98-4050).



The following are some of the examples of PEALD processes employing Strem supplied TDMASn precursor presented by diverse groups of researchers. 

Hoffmann et. al. report the preparation of transparent conductive gas permeation barriers based on thin films of tin oxide (SnOx) grown by spatial atomic layer deposition (ALD) at atmospheric pressure. They present a comparative study using tetrakis(dimethylamino)tin(IV) and various oxidants (atmospheric pressure oxygen plasma, ozone, and water) at process temperatures in the range of 80–165°C. (Link)



Recent reports by researchers from the Eindhoven University of Technology in collaboration with the Netherlands Organisation for Applied Scientific Research (TNO), present an extensive characterization of plasma-assisted atomic-layer-deposited SnO2 layers. They aim at identifying key material properties of SnO2 to serve as an efficient electron transport layer in perovskite solar cells. The SnO2 thin films were deposited at substrate temperatures of 50, 100, 150, and 200°C on Czochralski polished c-Si (100) wafers and indium tin oxide (ITO) glass substrates in an Oxford Instruments OpAL ALD reactor using tetrakis(dimethylamino)tin (TDMASn) (99% purity, Strem Inc.) as the tin precursor and radio-frequency (RF) inductively coupled oxygen plasma as the co-reactant.

Figure 3: Perovskite solar cells are one of the most promising emerging cell technologies with fast recent improvement in cell efficiency shown above red/yellow circles reaching >22% cell efficiency (From Wikimedia Commons, the free media repository).


An American researcher from University of Maryland, U.S. Naval Research Laboratory and Sandia National Lab, has reported the experimental realization of fully conformal 3D thin-film solid-state batteries (3D TSSBs) incorporating a SnNx anode (deposited at 200°C using TDMASn and an N2 plasma), demonstrating the simultaneous power-and-energy benefits of 3D structuring. All active battery components—electrodes, solid electrolyte, and current collectors—were deposited by atomic layer deposition (ALD) onto standard CMOS processable silicon wafers. The wafers were microfabricated to form arrays of deep pores with aspect ratios up to approximately 10. Their work shows that the exceptional conformality of ALD, combined with conventional semiconductor fabrication methods, provides an avenue for the successful realization of long-sought 3D TSSBs which provide power performance scaling in regimes inaccessible to planar form factor cells.
