top-down lithography
Top-down lithography is a manufacturing process used to create small structures on materials, commonly in the semiconductor industry. It involves starting with a larger material, such as a silicon wafer, and carving out the desired designs using light or other methods. This process allows for precise patterns to be etched onto the surface, forming components like microchips. Essentially, it’s like sculpting—removing excess material to reveal the intricate details that are needed for electronic devices, rather than building them up layer by layer. This technique is crucial for developing modern technology.

Top-Down Lithography is a manufacturing process used to create intricate patterns on materials, often for microchips and electronic components. It works by starting with a larger piece of material and then etching or cutting away unwanted parts to form the desired shapes. This technique can involve light exposure or chemical processes to define patterns on a surface. It enables precise control over size and design, making it essential for modern technology. In essence, it's like sculpting, where the final product emerges from a larger block by removing excess material.

Top-down lithography is a manufacturing process used to create tiny structures, typically in the fields of electronics and nanotechnology. It starts with a larger material, like silicon, and etched or patterned to form smaller features. The process involves applying a light-sensitive material on the surface, exposing it to light through a mask, and then chemically removing unexposed parts. This technique allows precise control over the size and shape of the patterns, enabling the production of complex devices such as microchips and sensors. The term "top-down" signifies that it begins from a larger substrate and carves down to create the desired features.
