What is the working principle of an electron beam lithography machine?

Electron beam lithography (EBL) is a micro-nano fabrication device based on electron beam exposure. Its core principle is to draw nano-scale patterns on a resist (such as PMMA, HSQ) using a high-energy electron beam. Finally, the pattern is transferred to the substrate material through processes such as development and fixing.

What is maskless lithography? How does it work?

Maskless lithography is an advanced lithography equipment that does not require a physical mask. It uses a digital micromirror device (DMD) to dynamically generate lithographic patterns, enabling flexible and efficient micro-scale structure processing. Its core function is utilizing the spatial light modulation capability of the DMD to directly project computer-designed patterns onto the substrate surface. This eliminates the cumbersome steps of mask making and alignment in traditional lithography, significantly shortening the R&D cycle and reducing production costs.
