Multi-project wafer service

Multi-project wafer service is a way for people to share one big chunk of silicon, called a "wafer". When the wafer is made, it is split up into many small pieces (called dies), each of which is then used by a separate person for a different project. This saves time, money, and resources because it means more people can do more projects on the same wafer.
