Polarization-ratio reflectance measurements in the extreme ultraviolet.
We demonstrate a technique for determining optical constants of materials in the extreme UV from the ratio of p-polarized to s-polarized reflectance. The measurements are based on laser-generated high-order harmonics, which have easily rotatable linear polarization but that are prone to brightness fluctuations and systematic drifts during measurement. Rather than measure the absolute reflectanc...
متن کاملAn Extreme Ultraviolet Spectrometer
A concept and preliminary design of an Extreme Ultraviolet (EUV) spectrometer is presented. The spectrometer is based on a gas ionization chamber and an advanced eight-electrode electron focusing system to form a narrow electron beam on a photodiode aperture. The design is modeled with the SIMulation of IONs (SIMION) tools and shows the ability to scan through the spectral range of 20.0 – 40.6 ...
متن کاملExtreme - ultraviolet laser metrology of O I transitions
Some 16 transitions in atomic oxygen originating from its 3P ground state were measured using a tunable narrow-band extreme-ultraviolet laser source, with an unprecedented accuracy of λ/λ= 8× 10−8. The results are relevant for comparisons with spectral absorption features observed in the line of sight of quasars, in order to test a possible variation of the fine-structure constant α on a cosmol...
متن کاملSystem-level line-edge roughness limits in extreme ultraviolet lithography
As critical dimensions shrink, line edge and width roughness (LER and LWR) become of increasing concern. Traditionally LER is viewed as a resist-limited effect; however, as critical dimensions shrink and LER requirements become proportionally more stringent, system-level effects begin to play an important role. Recent advanced EUV resist testing results have demonstrated lower bounds on achieva...
متن کاملExtreme ultraviolet frequency comb metrology.
The remarkable precision of frequency-comb (FC) lasers is transferred to the extreme ultraviolet (XUV, wavelengths shorter than 100 nm), a frequency region previously not accessible to these devices. A frequency comb at XUV wavelengths near 51 nm is generated by amplification and coherent up-conversion of a pair of pulses originating from a near-infrared femtosecond FC laser. The phase coherenc...
