Here's Everything You Need To Know About X-Ray Lithography
India, April 27 -- What Is X-Ray Lithography?
X-ray lithography is a high-resolution patterning technique to fabricate micro and nanoelectronic devices. It employs X-ray radiation with wavelengths between 0.4 and 4 nanometres to transfer geometric patterns from a mask onto a light-sensitive resist layer deposited on a substrate, typically silicon.
How Does X-Ray Lithography Work?
X-ray lithography works similarly to photolithography but with X-rays. The following is a step-by-step breakdown:
Substrate Preparation: A thin layer of resist is deposited on the substrate, typically a silicon wafer.
Mask Making: An X-ray mask containing the desired circuit pattern is created. This mask is similar to a photographic negative, with the desire...
