Advanced photomask fabrication by e-beam lithography for mask aligner applications

open access: yes, 2022
Paper 1003204Photomasks contain geometric information that will be transferred to substrates or pre-structured surfaces. Conventional mask aligner lithography in the sense of shadow printing of the photomask suffers from limited achievable resolution ...

An ice lithography instrument [PDF]

open access: yesReview of Scientific Instruments, 2011
We describe the design of an instrument that can fully implement a new nanopatterning method called ice lithography, where ice is used as the resist. Water vapor is introduced into a scanning electron microscope (SEM) vacuum chamber above a sample cooled down to 110 K. The vapor condenses, covering the sample with an amorphous layer of ice.

Methodology for Fabrication-Tolerant Planar Directional Couplers

open access: yesIEEE Photonics Journal, 2022
A new methodology for realizing fabrication-tolerant planar directional couplers is proposed and experimentally demonstrated. Performance of power splitting and WDM couplers can be made highly tolerant to typical process errors when an appropriate center-

Lithography-free directional control of thermal emission

open access: yes, 2022
Blackbody thermal emission is spatially diffuse. Achieving highly directional thermal emission typically requires nanostructuring the surface of the thermally emissive medium. The most common configuration is a subwavelength grating that scatters surface

Rolling Nanoelectrode Lithography [PDF]

open access: yesMicromachines, 2020
Non-uniformity and low throughput issues severely limit the application of nanoelectrode lithography for large area nanopatterning. This paper proposes, for the first time, a new rolling nanoelectrode lithography approach to overcome these challenges. A test-bed was developed to realize uniform pressure distribution over the whole contact area between ...

Copper gallium selenide thin films on Si by magnetron sputtering for photovoltaic applications: Composition, junction formation and metal contacts

open access: yesCogent Engineering, 2018
Thin films of CuGaSe were deposited on n-Si (1 0 0) by rf magnetron sputtering from a stoichiometric CuGaSe2 target. The objective of this study was to characterize the thin film/Si heterojunction for potential photovoltaic applications, evaluate ...
