Small field lithography
WebbIn the small open areas of predefined surface structure GaP nanowires were grown. We demonstrate capabilities of near-field scanning optical microscopy (NSOM) in collection and illumination mode. NSOM in collection mode was used for high resolution characterization of optical field of patterned light emitting diodes. WebbThe effect of focus on a projection lithography system (such as a stepper) is a critical part of understanding and controlling a lithographic process. As feature sizes decrease, ... Many people would say that this focus sensitivity is the main limitation of the use of optical lithography for smaller and smaller features. This column
