Additive manufacturing (3D printing) has not been applicable to micro- and nanoscale engineering due to the limited resolution. Atomic layer deposition (ALD) is a technique for coating large areas with atomic thickness resolution based on tailored surface chemical reactions. Thus, combining the principles of additive manufacturing with ALD could open up a completely new field of manufacturing. Indeed, it is shown that a spatially localized delivery of ALD precursors can generate materials patterns. In this “atomic-layer additive manufacturing” (ALAM), the vertical resolution of the solid structure deposited is about 0.1 nm, whereas the lateral resolution is defined by the microfluidic gas delivery. The ALAM principle is demonstrated by generating lines and patterns of pure, crystalline TiO2 and Pt on planar substrates and conformal coatings of 3D nanostructures. The functional quality of ALAM patterns is exemplified with temperature sensors, which achieve a performance similar to the industry standard. This general method of multimaterial direct patterning is much simpler than standard multistep lithographic microfabrication. It offers process flexibility, saves processing time, investment, materials, waste, and energy. It is envisioned that together with etching, doping, and cleaning performed in a similar local manner, ALAM will create the “atomic-layer advanced manufacturing” family of techniques.

Atomic layer 3D printing awarded with 3 million EUR funds by EU

European consortium led by FAU receives funding from the European Union in the 'Fast Track to Innovation' programme

The prospects of additive manufacturing (3D printing) as a versatile tool for prompt and inexpensive prototyping are extremely promising. This family of methods are set to make fabrication processes faster, more efficient in terms of the raw materials and energy required, and more flexible. However, additive manufacturing has not yet been broadly applied to micro and nanotechnology. Lithography, as the methods used for structuring in microelectronics are called collectively, is based on the repetition of complex multistep procedures in each of which a so-called "resist" that serves as a template is applied and later removed. Not only is current lithography slow, it also wastes materials and energy, is poorly adapted to combining a large number of distinct materials, and extremely costly in terms of capital expenses.

A team of scientists and engineers led by Prof. Julien Bachmann from FAU plan to combine the expertise of the various consortium partners in the chemical control of ultrathin coatings ("atomic layer deposition"), in gas delivery, microelectromechanical devices, and microprocessing and automation, in order to demonstrate the potential of "atomic-layer 3D printing", that is, the generation of arbitrary shapes with a vertical resolution in the order of one atom (or a tenth of one nanometer).

The consortium includes the companies ATLANT 3D Nanosystems, Femtika, and SEMPA Systems as well as the Institute of Electrical Engineering of the Slovak Academy of Sciences and FAU, and will be funded by approximately 3 million euros over a period of two years in the framework of the European Union's "Fast Track to Innovation" programme. The goal of the project is to design, build and test an industrial prototype of the atomic-layer 3D printer that can then be sold commercially.

ATLANT3D demonstrate high precision ALD printing

ATLANT3D report that they have completed successfully testing of their atomic printing system and could print first simple geometries and patterns. ATLANT3D technology relies on selective area direct atomic layer deposition process and enables direct pattern generation with atomic precision at 20 nm and 100-400 micrometer lateral resolution. 

Next chance to meet ATLANT3D will be at EFDS ALD for Industry 2020 in Freiburg April 1, 2020 (LINK) where CEO & Founder Dr. Maksym Plakhotnyuk will present "Direct atomic pattern printing"
