Photolithography (also known as optical lithography) is a process that involves using light to transfer a pattern onto a photoresist layer deposited on a sample, typically a silicon wafer.

Sep 29, 2025 · When manufacturing a surface via photolithography, there are five fundamental processes involved: substrate preparation, photoresist application, soft baking, mask alignment and …

Aug 21, 2025 · Photolithography is the process of coating a substrate with photoresist, exposing it to light through a mask to form a pattern, and then developing the pattern by either removing …

In general, modern photolithography involves a procedure with six steps: In photolithography, a wafer is a thin slice of semi conductive material, such as crystalline silicon, that forms the base for the …

Photolithography engineers must identify the optimal photoresist for their specific process - including exposure wavelength, patterning stack, thickness, and resolution requirements.

Photolithography is the process of transferring the geometric shape of a mask onto the surface of a substrate using a photoresist solution, which is exposed to UV light through the mask, followed by a …

II – Photolithography steps From the application to the removal of the photoresist, the photolithography sequence generally includes the following steps :
