Abstract
A lithography method in semiconductor fabrication is provided. The method includes generating a plurality of drops of a target material through a plurality of nozzles, adjacent two of the plurality of nozzles having a distance less than a width of a first one of the adjacent two of the plurality of nozzles, wherein the plurality of drops are aggregated to an elongated droplet; generating a laser pulse to convert the elongated droplet into plasma that generates an extreme ultraviolet (EUV) radiation; exposing a semiconductor substrate to the EUV radiation.
