Spatial coherence properties of an LED-based illumination system for mask-aligner lithography

Hans Peter Herzig, Toralf Scharf, Wilfried Noell, Raoul Kirner, Johana Bernasconi

A high-power LED-based illumination system has been developed as a replacement for the mercury arc lamps used in mask-aligner lithography. LEDs are arranged in a grid array and placed in the entrance aperture of individual reflectors. Those reflectors decr ...

Printing sub-micron structures using Talbot mask-aligner lithography with a 193 nm CW laser light source

Toralf Scharf, Wilfried Noell, Raoul Kirner, Andreas Vetter

A continuous improvement of resolution in mask-aligner lithography is sought after to meet the requirements of an ever decreasing minimum feature size in back-end processes. For periodic structures, utilizing the Talbot effect for lithography has emerged a ...

High-power modular LED-based illumination systems for mask-aligner lithography

Hans Peter Herzig, Toralf Scharf, Johana Bernasconi

Mask-aligner lithography is traditionally performed using mercury arc lamps with wavelengths ranging from 250 nm to 600 nm with intensity peaks at the i, g and h lines. Since mercury arc lamps present several disadvantages, it is of interest to replace the ...

Development of a Localization System Based on VLC Technique for an Indoor Environment

Kwang Moo Yi

In this paper, we develop an indoor localization device which embeds localization information into indoor light-emitting-diodes (LED) lighting systems. The key idea of our device is the use of the newly proposed "bit stuffing method". Through the use of st ...

Determinants of disinfectant pretreatment efficacy for nitrosamine control in chloraminated drinking water

Urs von Gunten

Utilities using chloramines need strategies to mitigate nitrosamine formation to meet potential future nitrosamine regulations. The ability to reduce NDMA formation under typical post-chloramination conditions of pretreatment with ultraviolet light from a ...

Light wavelength-dependent E. coli survival changes after simulated solar disinfection of secondary effluent

César Pulgarin, Sami Rtimi, Stefanos Giannakis

In this study, the photoreactivation and the modification of dark repair of E. coli in a simulated secondary effluent were investigated after initial irradiation under different conditions. The simulated solar exposure of the secondary wastewater was follo ...

Les mécanismes de lumière naturelle: analyse des bibliothèques d'Alvar Aalto. (Prix IBE-BIV 2013, Institut Belge de l'éclairage, affilié à la CIE)

Jean-Denis Bernard Marie Ghislain Thiry

Today, the challenges of sustainable development require revisiting all the parameters of architectural design. According to the International Energy Agency , in 2005, 19% of the electricity produced in the world was consumed for lighting. We know that the ...

Localization of MAP1-LC3 in Vulnerable Neurons and Lewy Bodies in Brains of Patients With Dementia With Lewy Bodies

Darren Moore

There is emerging evidence implicating a role for the autophagy-ysosome pathway in the pathogenesis of Lewy body disease. We investigated potential neuropathologic and biochemical alterations of autophagy-lysosome pathway-related proteins in the brains of ...
