Atomic layer deposition – the intersection of materials science, physics, chemistry and industry

There are thousands of techniques of making materials. But how can something be made, that is so small, it is not even visible under a regular optical microscope? For example, today’s electronics industry routinely makes thin films that have a thickness of 100 nanometers (nm), 50 nm or even 3 nm. And how is such a material studied, for determining a novel material in a research laboratory or performing quality control in a company? How can one measure a material’s thickness and composition if it’s thickness is a mere 10 nm, for example?

Atomic Layer Deposition (ALD) is a thin-film deposition technique that plays a critical role in advancing modern technologies, from semiconductors and energy storage to coatings for medical devices and optics. Its unique ability to deposit ultra-thin films with atomic-level precision makes it a cornerstone of innovation in nanotechnology and materials science. Most computers, solar panels and mobile phones have some details in them made using ALD. But the fun doesn’t stop at currently existing technologies. Scientists and engineers are constantly working to find new ways how to utilize thin films made by ALD in various new technologies, such as neuromorphic computing that is advancing AI.

This course offers participants a rare opportunity to explore ALD and it’s applications in depth, blending theoretical knowledge with hands-on experience. You will not only learn the principles and applications of ALD but also operate equipment to perform your own film depositions. Beyond that, you'll gain experience in characterization techniques, including spectroscopic ellipsometry, X-ray diffraction (XRD), and scanning electron microscopy (SEM), to analyze the structure, composition, and properties of the deposited films. 

At the conclusion of the course, you will collaborate in groups to compile your findings and theoretical knowledge into a comprehensive project report. This report will be presented to other groups and will include a detailed description of the project's background, a summary of your results, and a concluding discussion, including potential applications of the films you have deposited.
