In October 2025, ASML made a significant announcement: the delivery of its inaugural TWINSCAN XT:260 lithography system. This system is tailored explicitly for advanced packaging, providing solutions to the challenges encountered in semiconductor heterogeneous integration and advanced packaging processes. The XT:260 employs an i-line light source, achieving a resolution of 400 nanometers. When compared to existing similar devices, it boasts a remarkable fourfold increase in production efficiency, with the capability to process up to 270 wafers per hour. One of the standout features of the XT:260 is its exceptionally large exposure field, measuring 26x33 millimeters. Additionally, it utilizes a 2x mask reduction technique. These characteristics render it highly suitable for applications in interposers, 3D Integrated Circuits (3DICs), and Co-Packaged Optics (CPOs). Its dual-stage architecture, combined with dynamic focusing capabilities, empowers it to effectively handle warped wafers. This not only enhances production efficiency and yield but also serves as a driving force for advancements in semiconductor technology.
