Lawrence Livermore National Laboratory (LLNL) has long pioneered the development of EUV lithography, including early spectroscopic studies that formed the foundation of plasma-based EUV sources.
LLNL is advancing semiconductor manufacturing with its groundbreaking Big Aperture Thulium (BAT) laser, which promises to boost the energy efficiency of extreme ultraviolet (EUV) lithography by tenfold compared to existing carbon dioxide (CO2) lasers. This development could pave the way for “beyond EUV” (BEUV) lithography, enabling the production of smaller, faster, and more energy-efficient chips. Building on five years of foundational research, LLNL will pair the compact high-repetition-rate BAT laser with innovative technologies to optimize EUV light generation, potentially transforming chip production and fields like high-energy density physics and inertial fusion energy. While these initial demonstrations show promise, the technology has not yet been proven in a full-scale, operational context for EUV or BEUV lithography. The current project aims to further test and refine the BAT laser’s capabilities, particularly its potential to improve energy efficiency and scalability for semiconductor manufacturing.
My Take
The shift toward BEUV lithography reflects the semiconductor industry’s relentless drive for innovation. If successful, this LLNL initiative could redefine efficiency standards and create new opportunities for scaling EUV.
