WebA recent review of EUV lithography has been published by Wu and Kumar [206]. Another limitation is that the side walls of the generated structures are usually perpendicular to the substrate surface. Hence, while laterally the shape can be chosen freely, the side walls cannot. To overcome this limitation, some effort has to be done.
