Numerical aperture and wavelength
WebNA the numerical aperture. According to this equation, the resolution of a lithography tool – and thus its ability to print features with a certain half pitch or critical dimension (CD) – can be improved by using light with smaller wavelength during wafer exposure. WebThe numerical aperture of a microscope objective is a measure of its ability to gather light and resolve fine specimen detail at a fixed object distance. Image-forming light waves pass through the specimen and …
