Extreme Ultraviolet Source Based on Microwave Discharge Produced Plasma Using Cavity Resonator
D2-PMo-1 APPC12 The 12th Asia Pacific Physics Conference Extreme Ultraviolet Source based on microwave discharge produced plasma using cavity resonator S. Tashima, M. Ohnishi, H. Osawa, W. Hugrass a Department of Electrical and Electronic Engineering, Faculty of Engineering Science, Kansai University, 3-3-35 Yamate-cho, Suita, Osaka 564-8680, Japan aSchool of Computing and Information Systems, University of Tasmania, Locked Bag 1359, Launceston, Tasmania 7250, Australia [email protected] Extreme ultra violet (EUV) lithography is a leading technology for the production of the next-generation chips with small features. The 13.5-nm EUV radiation can be obtained using either discharge-produced plasma (DPP) or laser-produced plasma (LPP) sources. Because the EUV radiation is strongly absorbed by all known materials, the entire EUV scanner system must be in a vacuum environment. The debris and the tin vapor generated in some EUV sources may cause contamination of the EUV mirrors and the silicon wafers. The microwave discharge produced plasma (MDPP) source invented at Kansai University does not produce debris because it is electrode-less and the working gas is Xe.. Figure 1 shows the photo of MDPP. The microwave frequency is 2.45 GHz, the maximum power (Prf ) is 6 kW and the cavity mode is TM110. The Xe gas is fed in a glass tube with inner diameter 3 mm. The EUV radiation is measured using a calorie meter and EUV spectroscopy. The preliminary experiments show that the Figure 1 The system of microwave discharge produced plasma system MDPP produces pulsed EUV radiation of 10 W/4π str. -
Extreme-Ultraviolet Frequency Combs for Precision Metrology and Attosecond Science
REVIEW ARTICLE https://doi.org/10.1038/s41566-020-00741-3 Extreme-ultraviolet frequency combs for precision metrology and attosecond science Ioachim Pupeza 1,2 ✉ , Chuankun Zhang3,4, Maximilian Högner 1 and Jun Ye 3,4 ✉ Femtosecond mode-locked lasers producing visible/infrared frequency combs have steadily advanced our understanding of fundamental processes in nature. For example, optical clocks employ frequency-comb techniques for the most precise measure- ments of time, permitting the search for minuscule drifts of natural constants. Furthermore, the generation of extreme-ultraviolet attosecond bursts synchronized to the electric field of visible/infrared femtosecond pulses affords real-time measurements of electron dynamics in matter. Cavity-enhanced high-order harmonic generation sources uniquely combine broadband vacuum- and extreme-ultraviolet spectral coverage with multimegahertz pulse repetition rates and coherence properties akin to those of frequency combs. Here we review the coming of age of this technology and its recent applications and prospects, including precision frequency-comb spectroscopy of electronic and potentially nuclear transitions, and low-space-charge attosecond-temporal-resolution photoelectron spectroscopy with nearly 100% temporal detection duty cycle. he control over broadband visible/near-infrared (VIS/NIR) ωN = ω0 +Nωr.

A Theoretical Investigation

Soc. Burlington House, Piccadilly London W1J 0BQ [email protected] September 6, 2019 ABSTRACT With new discoveries and insights in atomic and optical physics, the field of spectroscopy is advancing to a new level with applications ranging from material science to astronomy. We here propose a theoretical description of a potential new phenomenon resulting from the extension of Compton’s experiment on the scattering of high energy photons through atomic electrons. How the proposed phenomenon can be tested experimentally is discussed in the paper as well.∗ ∗The Idea of the paper is to be presented as part of an International Conference talk (ICECMP-2019) © 2019 by the author(s).

Single-Atom Gating of Quantum State Superpositions

The ultimate miniaturization of electronic devices will likely require local and coherent control of single electronic wavefunctions. Wavefunctions exist within both physical real space and an abstract state space with a simple geometric interpretation: this state space—or Hilbert space—is spanned by mutually orthogonal state vectors corresponding to the quantized degrees of freedom of the real-space system. Measurement of superpositions is akin to accessing the direction of a vector in Hilbert space, determining an angle of rotation equivalent to quantum phase. Here we show that an individual atom inside a designed quantum corral1 can control this angle, producing arbitrary coherent superpositions of spatial quantum states. Using scanning tunnelling microscopy and nanostructures assembled atom-by-atom2 we demonstrate how single spins and quantum mirages3 can be harnessed to image the superposition of two electronic states. We also present a straightforward method to determine the atom path enacting phase rotations between any desired state vectors. A single atom thus becomes a real- space handle for an abstract Hilbert space, providing a simple technique for coherent quantum state manipulation at the spatial limit of condensed matter. -
