Xanadu, a world leader in photonic quantum computing, and Mitsubishi Chemical, have launched a joint project to use quantum computing for the advancement of new semiconductor chip fabrication technologies. This collaboration aims to discover novel quantum algorithms for simulating quantum processes in extreme ultraviolet (EUV) lithography–a wafer patterning technique utilizing extremely short wavelength light–which is critical for developing ever-smaller and more complex microchips.
EUV lithography has emerged as a promising wafer patterning technique for facilitating the continued miniaturization of integrated circuits, which enables advanced technologies such as smartphones, supercomputers, and artificial intelligence. However, as feature sizes become smaller, quantum effects such as Auger decay become more important, which makes the lithographic process difficult to simulate due to complicated electron interactions. Quantum computing offers a pathway beyond this limitation due to its ability to directly simulate dynamics of quantum systems and light-matter interactions.
In this partnership, researchers from Mitsubishi Chemical‘s Materials Design Laboratory will provide deep expertise on EUV photoresist materials, including their molecular structures, compositions, and reactivity. They will offer a fundamental understanding and quantitative analysis of key physical processes such as EUV absorption, Auger decay, and secondary electron effects. The Quantum Algorithms team at Xanadu will provide quantum algorithms expertise in designing the simulation algorithms that model light-matter interactions and secondary electron effects.
