Märkäetsauksessa
Märkäetsauksessa, also known as "wet etching," is a chemical process used to selectively remove material from a substrate, typically in the manufacturing of electronic components, microelectromechanical systems (MEMS), and semiconductor devices. The technique involves immersing or applying a chemical solution—called an etchant—directly onto the material surface, where it reacts with specific constituents and dissolves them away.
The process is valued for its precision and ability to create intricate patterns and modifications at micro-
Common etching chemicals include acids, alkalis, and specialized formulations designed to target specific materials such as
Märkäetsauksessa offers advantages such as simplicity, cost-effectiveness, and the ability to process large areas uniformly. However,
This technique is widely utilized in microfabrication, often in combination with photolithography, where the chemical patterning
