X-ray lithography - Wikipedia
X-ray lithography is a process used in semiconductor device fabrication industry to selectively remove parts of a thin film of photoresist. It uses X-rays to transfer a geometric pattern from a mask to a light-sensitive chemical photoresist , or simply "resist," on the substrate to reach extremely small topological size of a feature.
X-Ray Lithography for Nanofabrication: Is There a Future?
2022年2月24日 · In this perspective article, we describe X-ray lithography’s latest advancements. First, we report the improvement in the fabrication of the high aspect ratio and high-resolution micro/nanostructures. Then, we present the radiation-assisted synthesis and processing of novel materials for the next generation of functional devices.
X-ray lithography: Some history, current status and future prospects ...
2016年8月1日 · X-ray lithography (XRL) is an extension of optical lithography to shorter wavelengths. Due to the difference in penetration and reflection of X-rays in matter, XRL is usually per- formed in a projection transmission proximity printing mode instead of the usual reflection mode (mask pattern imaging), used by optical lithography.
X-Ray Lithography - an overview | ScienceDirect Topics
X-ray lithography uses x-rays, characterized by a wavelength of 0.4–4 nm, usually generated by a synchrotron source, to expose a resist-coated sample through a proximity shadow mask. 24 Despite the high-resolution capabilities, this technique failed to provide an economically attractive lithographic process owing to the high tool costs. 25 ...
X-Ray Lithography - Integrated Circuit Fabrication - Academic …
In X-ray lithography an X-ray source illuminates a mask which casts a shadow on the resist. Overlaying the pattern, made out of X-ray absorbing material, on to a transmitting material, produces the mask used in X-ray lithography. Any materials to be used in the absorbing part of the mask must have high absorption coefficients in the X-ray region.
X-ray lithography is a technique for replicating patterns by shadow printing. HELIOS 1, a compact racetrack synchrotron forX- ray lithography, was assembled and tested prior to installation at IBM's semiconductor manufac turing facility at East Fiskill, NY, USA. (Photo Oxford Instruments.
