Photolithography
Photolithography is a microfabrication process used primarily in semiconductor manufacturing to pattern thin films and substrates. It involves using light to transfer a geometric pattern from a photomask to a light-sensitive chemical photoresist on a substrate, enabling the creation of intricate microstructures such as integrated circuits. This process is fundamental to producing computer chips, MEMS devices, and other microelectronic components.
Developers should learn about photolithography when working in hardware engineering, semiconductor design, or nanotechnology fields, as it is essential for fabricating microchips and electronic devices. It is used in scenarios requiring precise patterning at micrometer or nanometer scales, such as in CPU manufacturing, sensor development, and research labs focused on microelectronics. Understanding this process helps in designing circuits and collaborating with fabrication teams.
