Contact Printer

A contact printer is a tool used in the semiconductor industry to transfer patterns onto a substrate, such as a semiconductor wafer. The contact printer operates by pressing a template or mask, which has the desired pattern, against the substrate and exposing the substrate to a light source or energy source that causes a photochemical or thermal reaction. The photochemical reaction results in a change in the physical or chemical properties of the substrate, which allows for the transfer of the pattern. The thermal reaction is typically used for pattern transfer in high-temperature processes, such as during the deposition of tungsten. Contact printers are widely used in the semiconductor industry because they offer high accuracy and repeatability, making them suitable for the manufacture of high-density and high-performance semiconductor devices. They are also compatible with a wide range of materials and substrates, including silicon, glass, and plastic. The choice of a contact printer for a specific semiconductor manufacturing process depends on several factors, including the size of the substrate, the desired resolution of the pattern, and the specific requirements of the process, such as compatibility with high-temperature processing or exposure to certain light sources.
