What Techniques are Used to Ensure Tight Tolerances?
Several advanced techniques and technologies are employed to achieve and maintain tight fabrication tolerances:
Electron Beam Lithography (EBL): This technique uses focused beams of electrons to create extremely fine patterns. Atomic Layer Deposition (ALD): A thin film deposition technique that allows for precise control over layer thickness at the atomic level. Molecular Beam Epitaxy (MBE): A method for depositing single crystals with atomic precision. Self-Assembly Processes: Leveraging chemical and physical interactions to form well-defined nanostructures.
