This second page of the Semiconductor tag extends the collection of posts on optics for chip manufacturing and related processes. Additional articles further detail technologies for lithography, overlay and critical dimension metrology, and high-throughput inspection systems. Readers gain more nuanced perspectives on challenges like managing aberrations over large fields, maintaining focus at high numerical apertures, and controlling stray light in densely patterned wafers. For those deeply involved in semiconductor process and equipment development, this page offers further examples and technical discussions that build on the themes introduced on the first page. Together, both pages highlight the depth of optical expertise required to support advanced semiconductor manufacturing and how Avantier contributes to that ecosystem.
