We support both highly reproducible design using PDKs (Process Design Kits) and custom design tailored to customer specifications. With flexible choices of materials and structures, and one-stop support from design through prototyping and mass production, we comprehensively support metalens development from R&D to practical implementation. Why Choose SCIVAX Support for PDK-Based and Custom Design We provide PDKs (Process Design Kits) with pre-verified optical characteristics, allowing immediate use of process specifications, lens models, and design rules. In addition to standard PDKs, we flexibly support custom designs tailored to customer requirements, from specification studies through manufacturing. Optical Design Support We provide integrated support from optical analysis required for metalens design through lens design. Supported Wafer Sizes We support wafer sizes suited to each purpose, from R&D applications to mass production. Prototype and Mass-Production Foundry Services We respond flexibly from a single prototype wafer to mass production according to the development stage. We support production volumes of 1 to 100 wafers per month, from production launch through stable supply.
