Isotropic etching is useful for creating curved or sloped nanostructures, such as nanolenses or tapered nanowires. Anisotropic wet etching exhibits directional dependence, with faster etching in ...

Anisotropic wet etching Definition: The process of using strong acids/alkalis to remove a thin layer of the unprotected parts of a sample surface (e.g. metal or silicon) to create a pattern.

Anisotropic Etching: Dry etching can etch vertically down into the material, ... However, wet etching remains a valuable technique due to its simplicity and lower cost.

Isotropic Etching: Wet etching is typically isotropic, meaning that it etches material equally in all directions.This can lead to undercutting of the mask and loss of feature resolution. In contrast, ...

Anisotropic diamond etching through thermochemical reaction between Ni and diamond in high-temperature water vapour. Scientific Reports , 2018; 8 (1) DOI: 10.1038/s41598-018-25193-2 Cite This Page : ...

After years in R&D, several fab tool vendors last year finally began to ship systems based a next-generation technology called atomic layer etch (ALE). ALE is is moving into 16/14nm, but it will play ...
