What are the Techniques Used in Precision Engineering?
Several techniques are employed to achieve precision in nanotechnology:
1. Lithography: A process used to pattern parts of a thin film or the bulk of a substrate. Photolithography and electron beam lithography are popular methods. 2. Atomic Force Microscopy (AFM): Used to measure and manipulate materials at the nanoscale with atomic precision. 3. Scanning Tunneling Microscopy (STM): Allows for imaging surfaces at the atomic level and manipulating individual atoms. 4. Electron Beam Lithography (EBL): Uses a focused beam of electrons to create extremely fine patterns needed for nanoscale devices. 5. Focused Ion Beam (FIB) Machining: Enables nanoscale patterning and deposition by focusing a beam of ions onto a surface.
