WebLithography is used to develop nanostructures via a physical or chemical top-down approach. Chemical lithography is carried out using acid or bases or by using a heating … WebWhat you will do. Imec’s Sensors and Actuators Technology department is developing devices on glass and other non-traditional substrates for integration into tomorrow’s displays, imagers and biomedical applications. In this growing R&D activity, we are currently looking for an R&D engineer to support our Nanoimprint Lithography (NIL) projects.

Current challenges and opportunities for EUV lithography

In lithography, decreasing the wavelength of light source is the most efficient way to achieve higher resolution. Photoresists are most commonly used at wavelengths in the ultraviolet spectrum or shorter (<400 nm). For example, diazonaphthoquinone (DNQ) absorbs strongly from approximately 300 nm to 450 nm. The absorption bands can be assigned to n-π* (S0–S1) and π-π* (S1–S2) transitions in the DNQ molecule. In the deep ultraviolet (DUV) spectrum, the π-π* ele… WebCO 2 ‐Based Dual‐Tone Resists for Electron Beam Lithography Xin-Yu Lu, Hao Luo, Kai Wang, Yao-Yao Zhang, Xiao-Feng Zhu , et al Advanced Functional Materials 2024-03-01 31 (13): 2007417-2007417 被引量：4 iowa isics
