What are the MPW and DPW runs?

“An MPW is a Multi-Project Wafer run aimed at fast prototyping and design testing. Multiple clients submit their designs to the same batch and share the wafer space, which helps reduce costs, while preserving design confidentiality. In MPW runs, the vertical stack (i.e., the material layer thicknesses, arrangements, and processing methods) is fixed to a known-good configuration, maintained by Luxtelligence.”
