Patent number: 9538628Abstract: The present disclosure relates to an extreme ultraviolet (EUV) radiation source that generates charged tin droplets having a trajectory controlled by an electromagnetic field, and an associated method. In some embodiments, the EUV radiation source has a laser that generates a laser beam. A charged fuel droplet generator provides a plurality of charged fuel droplets having a net electrical charge to an EUV source vessel. An electromagnetic field generator generates an electric field and/or a magnetic field. The net electrical charge of the charged fuel droplets causes the electric or magnetic field to generate a force on the charged fuel droplets that controls a trajectory of the charged fuel droplets to intersect the laser beam. By using the electric or magnetic field to control a trajectory of the charged fuel droplets, the EUV system is able to avoid focus issues between the laser beam and the charged fuel droplets.Type: GrantFiled: June 11, 2015Date of Patent: January 3, 2017Assignee: Taiwan Semiconductor Manufacturing Co., Ltd.Inventors: Tsiao-Chen Wu, Jaw-Jung Shin
