Optical lithography is a process used to create integrated circuits on silicon wafers. It involves coating the wafer with light-sensitive resist, exposing it to focused beams of visible or UV light through photomasks, and etching the surface. The resist can be positive or negative, and photomasks can be used in contact printing, proximity printing, or […]
Offset lithography is a fast, efficient, and cheap printing technique used for books, newspapers, and magazines. It involves making a flat plate with the image to be printed, which is then transferred onto paper using rollers covered in ink and water. The process can be sheet-fed or roll-fed and produces high-quality images. The first offset […]
