Lithography pitch

WebIn such process, the resolution formula may be expressed as CD = k 1 xλ/NA, where λ is the wavelength of radiation employed, NA is the numerical aperture of the projection optics in the lithographic apparatus, CD is the “critical dimension” (generally the smallest feature size printed, but in this case half-pitch) and ki is an empirical resolution factor. Webpitch: [noun] a black or dark viscous substance obtained as a residue in the distillation of organic materials and especially tars.
