摘要： Disclosed herein are systems and methods for extending one or both of the discharge electrodes in a transverse discharge gas laser chamber in which one or both the electrodes are subject to a dimensional change due to erosion. Electrode extension can be performed to increase the chamber life, increase laser performance over the life of the chamber, or both. Operationally, the inter-electrode spacing may be adjusted to maintain a specific target gap distance between the electrodes or to optimize a specific parameter of the laser output beam such as bandwidth, pulse-to-pulse energy stability, beam size, etc.

摘要： An injection seeded modular gas discharge laser system (2) capable of producing high quality pulsed beams at pulse rates of about 4,000 Hz or greater and at pulse energies of about 5 mJ or greater. Two separate discharge chambers are provided, one of which is a part of a master oscillator (10) producing a very narrow band seed beam, which is amplified (12) in the second discharge chamber. The chambers can be controlled separately permitting separate optimization of wavelength parameters in the master oscillator and optimization of pulse energy parameters in the amplifying chamber. A preferred embodiment in the ArF excimer laser system configured as a MOPA and specifically designed for use as a light source for integrated circuit lithography. In the preferred MOPA embodiment, each chamber comprises a single tangential fan (10A) providing sufficient gas flow to permit operation at pulse rates of 4,000 Hz or greater by cleaning debris from the discharge region in less time that the approximately 0.25 milliseconds between pulses. The masters oscillation is equipped with a line narrowing package having a very fast tuning mirror capable of controlling centerline wavelength on a pulse-to-pulse basis at repetition rates of 4000 Hz or greater to a precision of less than 0.2 pm.

摘要： A high resolution etalon-grating spectrometer or monochromator. A preferred embodiment presents as extremely narrow slit function in the ultraviolet range and is very useful for measuring bandwidth of narrow band excimer lasers used for integrated circuit lithography. Light from the laser is focused into a diffuser (D) and the diffused light exiting the diffuser illuminates an etalon (ET). A portion of its light exiting the etalon is collected and directed into a slit positioned at a fringe pattern of the etalon. Light passing through the slit is collimated (L3) and the collimated light illuminates a grating (GR1) positioned in an approximately Littrow configuration which disperses the light according to wavelength. A portion of the dispersed light representing the wavelength corresponding to the selected etalon fringe is passed through a second slit (2) and monitored by a light detector (PMT). When the etalon and the grating are tuned to the same precise wavelength a slit function is defined which is extremely narrow as about 0.034pm "FWHM" and about 0.091pm "95 percent integral". The etalon and the grating are placed in a leak-tight containment (50) filled with a gas, such a nitrogen or helium.
