Atomschicht

Atomschicht refers to the thin film deposition process where material is added one atomic layer at a time. This precise control over thickness allows for the creation of extremely thin and uniform layers, often measured in nanometers or even angstroms. The technique is crucial in various advanced manufacturing fields, particularly in the semiconductor industry for creating integrated circuits.

The deposition process in Atomschicht typically involves alternating cycles of exposing the substrate to different precursor gases. Each gas reacts with the surface, forming a self-limiting monolayer of the desired material. After each precursor exposure, a purging step removes any excess reactants and byproducts before the next precursor is introduced. This cyclical nature ensures that deposition occurs only at the atomic layer level, preventing uncontrolled growth.

Atomschicht deposition, also known as Atomic Layer Deposition (ALD), offers several advantages. It provides excellent conformality, meaning it can coat complex three-dimensional structures uniformly, which is difficult to achieve with other thin-film techniques. ALD also allows for high precision in film thickness control, leading to reproducible and reliable material properties. Furthermore, it can be used to deposit a wide range of materials, including oxides, nitrides, and metals, making it a versatile tool for creating advanced materials with tailored properties. Its applications extend beyond semiconductors to areas like catalysis, optics, and energy storage.
