WebLithography is used to develop nanostructures via a physical or chemical top-down approach. Chemical lithography is carried out using acid or bases or by using a heating process while physical lithography is performed with the help of photons, electrons, and ions (Yu et al., 2013 ). WebModern chips can have up to 100 layers, which all need to align on top of each other with nanometer precision (called 'overlay'). The size of the features printed on the chip varies depending on the layer, which means that different types of lithography systems are used for different layers.
