lithographic resists

Lithographic resists are special materials used in the process of making tiny patterns on surfaces, like computer chips. When exposed to specific types of radiation (such as light or electrons), these resists undergo chemical changes that allow certain areas to be removed or protected during etching or deposition. This enables precise formation of complex, miniature structures necessary for electronic devices. Resists are chosen based on their sensitivity, resolution, and compatibility with fabrication methods, playing a critical role in ensuring the accuracy and quality of the final micro- or nanoscale components.
