Sputteringlike

Sputteringlike is a term used to describe a phenomenon that resembles or mimics the physical process of sputtering, but without the direct involvement of plasma. Sputtering itself is a process where energetic ions bombard a target material, causing atoms or molecules to be ejected from the surface. This ejected material is then deposited onto a substrate, often used for thin-film deposition.

In a "sputteringlike" process, similar atom or molecule ejection and deposition can occur through other mechanisms. This might include the use of high-energy neutral beams, laser ablation, or even certain chemical etching processes that result in the removal and subsequent redeposition of material in a way analogous to sputtering. The key distinction is the absence of the plasma discharge typically employed in physical vapor deposition (PVD) sputtering techniques.

These sputteringlike methods can be advantageous in specific applications where plasma damage to sensitive substrates needs to be avoided, or where different film properties can be achieved compared to traditional sputtering. For instance, laser ablation can be used to deposit films from a solid target without the need for vacuum environments or complex gas handling, making it a more portable or simpler deposition method in some scenarios. Understanding the nuances between true sputtering and sputteringlike phenomena is crucial for selecting the appropriate deposition technique for a given material and application.
