What is Photolithography?
Photolithography is a crucial process in the production of semiconductors that is used to create unpredictable models on silicon wafers. The communication begins with the utilization of a photoresist, a photosensitive material, to the external layer of the wafer. After that, ultraviolet light is passed through a mask that contains the desired pattern and is applied to the resist-coated wafer.
Photolithography accepts a basic part in the improvement of current development, enabling the formation of more unassuming, faster, and every one of the more striking electronic contraptions.
What is Photolithography?
For making perplexing examples on silicon wafers, photolithography is an urgent assembling process. It includes keeping a photosensitive material, called a photoresist, on the wafer’s surface. The resist-coated wafer is covered with a pattern-covered mask, which is illuminated by ultraviolet light.
The resist’s solubility is altered as a result of a chemical reaction brought on by the light’s selective exposure. The resulting improvement eliminates either the uncovered or unexposed districts, abandoning the ideal example. This cycle is rehashed on numerous occasions to make complex coordinated circuits that power our cutting-edge innovation.
