valotusmateriaaleja
Valotusmateriaaleja refers to materials used in the process of photolithography, a crucial technique in semiconductor manufacturing and the production of microelectronic devices. These materials are light-sensitive compounds that undergo chemical changes when exposed to specific wavelengths of light, typically ultraviolet radiation. The primary purpose of valotusmateriaaleja is to create intricate patterns on a substrate, such as a silicon wafer, which will later be etched or deposited upon to form circuits.
The most common types of valotusmateriaaleja are photoresists. Photoresists are broadly categorized into two groups: positive
The selection of valotusmateriaaleja depends on several factors, including the desired resolution, the wavelength of light
