This invention describes a system where extreme ultra-violet (EUV) radiation is patterned and projected onto a wafer using transmissive membrane optics while managing thermal absorption, membrane mechanical stability, and optical obscuration. This enables programmable or mask-based projection lithography using transmissive optical elements. Background: Advanced manufacturing increasingly operates at single digit nanometer scales, placing growing demands on imaging systems for resolution, alignment accuracy, throughput, and production time. Established projection designs are near their physical and economic limits, with added complexity causing increased sensitivity to heat, contamination, and mechanical instability. Material constraints and tight geometric requirements further limit design flexibility and weaken traditional scaling methods. Industry responses, such as higher numerical aperture optics, smaller exposure fields, and stricter environmental control, deliver incremental improvements but also raise system complexity and operating risk. To sustain further scaling, manufacturers are shifting toward projection architectures that divide the imaging task into smaller, independently optimized optical sections, reducing the dependence on a single monolithic.
