Introduction to Ion Beam Etching Equipment
Ion Beam Etching Machine of Si/SiO2/Metals Materials
Ion beam etching, also known as ion milling, is a non-selective and anisotropic dry etching technology. Its core principle involves using a broad, collimated high-energy ion beam generated by an ion source to bombard the workpiece surface in a vacuum environment, thereby removing material through physical sputtering. Unlike plasma etching, the sample is not directly exposed to the plasma, thus avoiding electrical damage and contamination caused by plasma and enabling better process control.
Summary and Analysis of Key Subsystems in Ion Beam Etching Systems
Ion Beam Etching Basic PrinciplesIon beam etching (IBE) is an advanced micro/nano fabrication technology that uses a high-energy ion beam to remove material from the surface, enabling precise pattern transfer.
The principle of ion beam etching involves a high-energy ion beam (typically argon ions) generated by an ion source, which bombards the material surface vertically or at an oblique angle. The high-energy ions collide with atoms on the material surface, causing atoms to be ejected and removing material layer by layer, thus achieving etching. This etching method can be performed without chemical reactions, belonging to a physical etching process. Structure diagram of ion beam etching equipment
