WebSince lithography for device fabrication involves the use of optical exposure to create the pattern, semiconductor lithography is commonly called "photolithography". As with the inspection and metrology techniques already discussed, photolithography is the technique of choice for patterning because it is optical, and thus enables small features and high … WebIn very few lens systems is image distortion as critical as in microlithography. Since the distortion in a lithographic objective is measured in nanometers, the common technique of using the chief ray to define image placement is not sufilcient. The centroid of a ray bundle gives a more accurate prediction of the actual lens distortion. Figure ... Web6 sep. 2024 · Our dual-waveband and tri-waveband LDI lens optimize the image quality completely and the transmittance, which is better than 80% during waveband from 360nm to 400nm while ensuring the image quality in the same time.
