photolithography

Light-based etching process

Photolithography is a process for transferring patterns onto a surface using light and light-sensitive chemicals.

A mask blocks light in specific areas, creating precise patterns on material coated with photoresist.

The technique is fundamental to manufacturing semiconductors and integrated circuits, where microscopic circuit patterns must be etched onto silicon wafers with extreme precision.
