What are the Techniques Used in Nanomanufacturing?
Several techniques are employed in nanomanufacturing, each suitable for different applications. Some of the most common methods include:
Top-Down Lithography: This method involves carving out nanoscale structures from larger pieces of material using methods such as electron beam lithography or photolithography. Bottom-Up Assembly: This technique builds structures atom-by-atom or molecule-by-molecule, often using chemical vapor deposition (CVD) or molecular self-assembly. Nanoimprint Lithography: This is a form of top-down method where a mold is used to imprint nanoscale patterns onto a substrate. Atomic Layer Deposition (ALD): This technique involves the deposition of atomic layers one at a time to create thin films with precise thickness control.
