Atomic substitution builds semiconductors as Korean team proves low-power device performance
A technology to selectively replace atoms in semiconductors to implement multiple electrical functions on a single thin film has been developed. The Ministry of Science and ICT said a team led by Jo Moon-ho (조문호) at the Institute for Basic Science developed a modular transistor fabrication method for 2D semiconductors. The team converted WSe2 at atomic-layer thickness and built transistors whose switching voltage approached the room-temperature limit, while also reducing energy barriers and demonstrating low-voltage operation.

China aims for 5 nm without EUV by 2029, unveils 2D semiconductor pilot line
Chinese semiconductor startup Yuanjiyue unveiled what it called the world’s first 8-inch pilot production line for 2D semiconductors and set a goal of developing 5 nm-class chips without EUV lithography by 2029. The company said the line supports the full process from material preparation to tape-out and signals a move beyond lab research. Chairman Bao Wenzhong said it aims to build a process equivalent to 90 nm silicon this year and develop a fully domestic process by 2029.

KAIST develops automated screening technology for 2D semiconductors
KAIST said on Wednesday its researchers developed a technology that automatically screens 2D semiconductors using only optical microscope images and connects the process to transistor fabrication. The joint study used molybdenum disulfide and differences in RGB brightness by thickness to automate selection and electrode design. Verified with atomic force microscopy, the method distinguished 3 to 8 layers, screened suitable samples from more than 120,000 flakes, and produced and analyzed 1,615 transistors.
