Etching is used in microfabrication to chemically remove layers from the surface of a wafer during manufacturing. Etching is a critically important process module, and every wafer undergoes many etching steps before it is complete. For many etch steps, part of the wafer is protected from the etchant by a "masking" material which resists etching. In some cases, the masking materia… WebApr 7, 2024 · After that, samples were ultrasonically cleaned in deionized water for 30 min, followed by acid etching for 22–25 s at 25 °C in a solution composed of HNO 3 (8%), HF (5.5%), and deionized water (86.5%) in a polytetrafluoroethylene beaker. Acid etching aimed to remove the extra aluminum oxide particles and reduce the surface roughness.
