Wafer Stepping

Wafer stepping is a precise process in semiconductor manufacturing where a silicon wafer is positioned under a lithography machine. The machine uses a pattern, like a detailed stencil, to project circuit designs onto the wafer’s surface. After each pattern exposure, the wafer is moved (or "stepped") to a new position to create complex layered circuits across its surface. This process ensures that microscopic features are accurately placed to build integrated circuits. Proper alignment during stepping is crucial for the functionality of the final electronic devices, making wafer stepping a fundamental step in producing modern microchips.
