Several techniques are employed in micromachining, each suitable for different applications and materials:
1. Photolithography: A process used to transfer patterns onto a substrate using light-sensitive photoresist and exposure to UV light. 2. Laser Micromachining: Utilizes high-intensity laser beams to ablate material with high precision. 3. Electrochemical Micromachining: Involves the removal of material through anodic dissolution in an electrolytic solution. 4. Ion Beam Milling: Uses focused ion beams to sputter material away from the surface.
