Etching Liquid

https://www.by-micro.com/etching-liquid.html

An etching agent is a chemical used in the semiconductor etching process to selectively remove or strip away the target film layer, creating a designed pattern. Wet etching is one of the most important techniques used in this process, relying on a chemical reaction between the etching agent and the target film layer to achieve precise results. Each type of film layer has a specifically tailored etchant to ensure optimal performance.

Applications

Etching agents are primarily used in two key industries: integrated circuit manufacturing and flat panel display production.

Integrated Circuit Manufacturing: During the fabrication of integrated circuits, semiconductor manufacturers need to create extremely fine patterns on wafers. Etching agents play a crucial role in this process by accurately transferring patterns from the photoresist, which is applied during the photolithography process, onto the underlying materials. This step is vital for building the intricate architecture of integrated circuits.

Flat Panel Display Manufacturing: In the production of flat panel displays, etching agents are used to etch circuit patterns onto film layers, ensuring that the display emits light correctly. Wet etching is commonly used in this field, with different target film layers requiring different etching agents. For instance, the molybdenum/aluminum metal layer typically uses an etchant made from a mixture of phosphoric acid, nitric acid, acetic acid, and additives like potassium nitrate or potassium chloride. In contrast, the copper metal layer requires an etchant composed of hydrogen peroxide and other additives.
