Events

On September 17, James Owen presented a talk at MNE 2024 entitled, “Breaking Tennant’s Law with Ultra-high Speed Atomic Precision Lithography“. His co-authors included Joshua B. Ballard, Ehud Fuchs, and John N. Randall (all from Zyvex Labs). The talk covered the limitations of existing lithography technology, such as EUV and E-beam lithography, and how the industry might move forward using a new technology: nanoimprint lithography.

On May 29, James Owen gave a talk at EIPBN 2024 entitled, “Next generation fabrication techniques for top gated qubits in silicon“. His co-authors included Joshua B. Ballard, Ehud Fuchs, John N. Randall from Zyvex Labs, Felix Beaudoin from Nanoacademic Technologies Inc, and Anthony J. Sigillito from the University of Pennsylvania. The talk described two methods of creating atomically-precise (or near atomically-precise) quantum computer architectures using scanning tunneling microscope lithography (STM). In one method, the patterns were functionalized into 2D delta layers. In the other method, the STM patterns were converted into nanoimprint templates for scalability.

In January of 2024, James Owen gave a talk at SPIE entitled, “Atomically Precise Advanced Manufacturing for 2D Bipolar Devices“. His co-authors included Robin Santini, Moutaz Haq, Ehud Fuchs, and John N. Randall from Zyvex Labs, and Richa Mishra and Reza Moheimani from the University of Texas at Dallas. The talk described the process for fabrication of bipolar dopant-based devices, such as p-n junctions and n-p-n bipolar junction transistors, which may have a number of advantages (such as improved gain-bandwidth product and low-noise operation). The overall process described has become known as Atomically Precise Advanced Manufacturing (APAM), which offers far better patterning precision than conventional techniques such as e-beam lithography.

On June 2, James Owen presented a talk at EIPBN 2023 entitled, “APAM 2D bipolar device fabrication“. His co-authors included Robert Santini, Ehud Fuchs, and John N. Randall (all from Zyvex Labs). The talk discussed the development of sample designs and patterning technology to improve the precision and throughput of atomic-scale STM lithography.

Annual Meeting of the University of Pennsylvania’s SINGH Center for Nanotechnology was held on Oct. 21, 2021. John Randall gave the keynote lecture entitled “Digital – Atomically Precise Manufacturing”.

On August 12, John Randall gave a plenary lecture at Oak Ridge National Laboratory’s 2021 Joint Nanoscience and Neutron Science User Meeting.  The talk was entitled: “Digital Atomic Scale Fabrication – A promising path to Atomically Precise Manufacturing” John’s co-authors included James H.G. Owen and Udi Fuchs.  The talk described Zyvex’s efforts at developing Hydrogen Depassivation Lithography as a digital atomic-scale fabrication device and how this and other technologies would pave the path to Atomically Precise Manufacturing and eventually a new exponential manufacturing trend that would achieve APM at the nanoscale and then maintain that precision as the product sizes were scaled up.  This could be considered an Inverse Moore’s Law.

On June 1, John Randall presented a talk at the EIPBN 2021 Virtual Conference entitled “Progress Toward 2D Nano Bipolar Junction Transistors”.  His co-authors included: J.H.G. Owen, E. Fuchs, and R. Santini  all from Zyvex Labs, and Nupur Navlakha – University of Texas at Austin.  The talk described recent progress to develop nanoscale bipolar junction transistors (BJTs) using Hydrogen Depassivation Lithography to create 2D delta doped layers of donor (P) and acceptor (B) dopants in a single buried (100) plane of Si.  The fabrication included degenerative implanted regions to allow easy ohmic contacts with the delta doped layers.  The 2D nanoscale BJTs potentially have very reproducible and extremely high gain-bandwidth performance, cryogenic operation, rad hardness and low noise. 

John Randall presented Virtually (if not virtuously) at the 2021 March Meeting of the APS. He was also part of the Division of Quantum Information (DQI) programming committee along with Michelle Simmons and Joris Keizer of the University of New South Wales and Richard Silver of NIST.  John’s Talk was entitled “Digital Hydrogen Depassivation Lithography for Improving Precision of Donor Placement in Si” and his co-authors were James H.G. Owen, Ehud Fuchs, Moutaz Haq, and Robin Santini all from Zyvex Labs.   The talk presented a new strategy for exposing 4 atom pixels (2 dimers along a dimer row) with a single current pulse from the tip. This has the advantages of providing a greater tip position tolerance, an opportunity to keep better alignment with the Si lattice and verifying that all H atoms are removed from the pixel. 

In March, 2021, Udi Fuchs presented a talk at Photonics West entitled “Identifying surface elements in STM images using Neural Networks”. The work is funded by the DOE and is a collaboration between zyvex Labs and Oak Ridge National Laboratories.  The work is intended to use machine learning to provide identification of key features in STM images: atomic step edges, H-passivated Si atoms, clean Si atoms, Si atom vacancies, and defects to be identified so that Hydrogen Depassivation Lithography can be automated. This is a productivity boost for single tip STM systems and an absolute necessity for highly parallel arrays of STM tips doing patterning.

On January 14, 2021, John Randall presented at the Oregon State University and Washington University Nano Engineered Systems Seminar Series.  His co authors were James H.G. Owen, Ehud Fuchs, Rahul Saini, Robin Santini, Moutaz Haq, and Bill Owen – Zyvex Labs, and Reza Moheimani – UT Dallas.  His talk was entitled: “Digital Atomic-Scale Fabrication: A new approach to Atomically Precise Manufacturing (Quantum Devices)”.

MRS Webinar on Single Atom Fabrication with Beams and Probes

27 September 2017, 11:00 am – 12:30 pm

Josh Ballard, Director of APM at Zyvex Labs presented a webinar on Scanning Tunneling Microscopy-based Fabrication

The two current reigning paradigms enabling nanotechnology are scanning probe microscopy and molecular machine devices. Presently, the nanoscience and nanotechnology communities are seeing the emergence of a third paradigm—the use of the atomically focused beam of a scanning transmission electron microscope (STEM) to control and direct matter on the atomic scale. The September issue of MRS Bulletin presents advances in electron- and ion-beam-based atomic fabrication on surfaces, in layered materials, and in three dimensions. The talks in this webinar expand upon the articles in the September MRS Bulletin issue.
