Microlithography is a technology used in manufacturing semiconductors. It replicates an image pattern from a photomask on to a silicon wafer coated with photoresist (a light sensitive material) the process involves light passing through the photomask and causing the photoresist to be exposed to the wafer thus creating a blueprint for the semiconductor material that will be deposited on it. The semiconductor materials are used to make chips. The same process can be used in creating displays where the blueprint is the photomask which is used for the pixels and for driving transistors o the display glass. This technique is also used in the fabrication of sensors, actuators and biomedical devices.

The process has benefited from the knowledge of organic chemistry and photo-induced organic transformation. Many manufacturers keep in mind some factors while manufacturing these products. Some of them include cleanliness and quality that can meet the requirements of clients worldwide. Uniformity of temperature matters a lot in the whole production as this will determine the features of each unit processes.
