Patent number: 9596743Abstract: A beam guiding apparatus includes a vacuum chamber that includes a target region arranged to receive a target material for generating EUV radiation. The vacuum chamber includes a first and second opening for receiving into the vacuum chamber a first and second laser beam, respectively. The first and second laser beam have different wavelengths. The beam guiding apparatus further includes a superposition apparatus arranged to superpose the first and second laser beams entering into the vacuum chamber through the first and second openings, respectively, for common beam guidance in the direction of the target region. The superposition apparatus comprises a first optical element configured to seal the first opening of the vacuum chamber in a gas-tight manner and transmit the first laser beam, or a second optical element configured to seal off the second opening of the vacuum chamber in a gas-tight manner and transmit the second laser beam.Type: GrantFiled: March 11, 2016Date of Patent: March 14, 2017Assignee: TRUMPF Lasersystems for Semiconductor Manufacturing GmbHInventor: Andreas Enzmann

Patent number: 8847182Abstract: The invention relates to extreme ultraviolet “EUV” radiation generating systems that include a vacuum chamber where a target material can be positioned at a target position for generation of EUV radiation, and a beam guiding chamber for guiding a laser beam from a driver laser device towards the target position. The EUV radiation generating apparatus includes an intermediate chamber which is arranged between the vacuum chamber and the beam guiding chamber, a first window which seals the intermediate chamber in a gas-tight manner for entry of the laser beam from the beam guiding chamber and a second window which seals the intermediate chamber in a gas-tight manner for exit of the laser beam into the vacuum chamber. The invention also relates to a method for operating the EUV radiation generating apparatus.Type: GrantFiled: March 15, 2013Date of Patent: September 30, 2014Assignee: TRUMPF Laser— und Systemtechnik GmbHInventors: Martin Lambert, Andreas Enzmann
