The lens is used to focus the sectioned UV light down to a smaller area on the chip. The smallest feature size capable of being written on the wafer is a function of the numerical aperture of the lens as well as the wavelength of the light.

What is soft-lithography?
So, an alternative and non-photolithographic method that we call soft lithography was developed. Because this method uses a patterned elastomer(e.g. PDMS(Poly DiMethyl Siloxane)) as the stamp, mold, or mask to generate micro-patterns and microstructures, it was titled as 'soft' lithography. As compared with photo-lithography, soft lithography has many kinds of strength.
