What is a Exposure device?

A lithography machine is a crucial piece of equipment used in the semiconductor manufacturing process to transfer fine circuit patterns onto silicon wafers. This is a key step in the creation of transistors and circuits on semiconductor chips, which require extremely precise and accurate patterns. The process, known as photolithography, uses light to etch microscopic circuit designs onto the wafer.

The basic operation of a lithography machine involves first coating the silicon wafer with a light-sensitive material called photoresist. A mask (a thin plate containing the circuit pattern) is placed over the wafer, and ultraviolet (UV) light is passed through the mask to expose the photoresist on the wafer. After exposure, the wafer is developed, and the exposed portions of the photoresist are removed, leaving the circuit pattern on the wafer's surface.

As semiconductor miniaturization progresses, the feature sizes of circuits continue to shrink. This has driven advancements in lithography technology, including the development of extreme ultraviolet (EUV) lithography machines, which enable the transfer of even finer circuit patterns on the nanoscale, facilitating the production of cutting-edge semiconductor chips.
