Posez n’importe quelle question sur les cours, conférences, exercices, recherches, actualités, etc. de l’EPFL ou essayez les exemples de questions ci-dessous.
AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
Increased flexibility in patterning becomes important for the engineering of advanced nano/micro-electro-mechanical systems (NEMS/MEMS). Surfaces to be structured are either mechanically unstable and/or (bio-) chemically functionalized, such as ultra-thin ...
Sub-micron lithography processes are continuously optimized for semiconductor products where the enormous market potential justifies investment in advanced methods and extremely sophisticated equipment. Due to the extreme process costs and due to the limit ...
A 2×2 microfluidic-based optical switch is proposed and demonstrated. The switch is made of an optically clear silicon elastomer, Polydimethylsiloxane (PDMS), using soft lithography. It has insertion loss smaller than 1 dB and extinction ratio on the order ...
A novel local illumination scheme for optical lithography is proposed. It is based on the excitation of a surface plasmon on a metal film incorporated into a polymer light coupling mask for contact lithography. The electromagnetic field associated with the ...
Sub-micron scale lithography methods using deep UV, X-ray or electron beams will allow for further progress in integrated circuit hardware manufacturing. The drawback of these high-end patterning methods however is firstly, the high cost of the equipment, ...
We compare three different approaches to high-resolution contact lithography with special emphasis on contrast mechanisms for subwavelength structures. Masks with protruding metal absorbers, masks with absorbers embedded in the transparent background, and ...
Light-coupling masks (LCMs) based on structured organic polymers that make conformal contact with a substrate can constitute an amplitude mask for light-based lithographies. The LCM is exposed through its backside, from where the light is differentially gu ...
We discuss the potential and limitations of Light-coupling masks for high-resolution subwavelength optical lithography. Using a three-dimensional fully vectorial numerical approach based on Green's tensor technique, the near-field distribution of the elect ...
We describe an approach to optical lithography using light-scattering contact masks with protruding elements that couple light into a photoresist. This method differs from conventional contact lithography in two important ways. First, because portions of t ...
