Lithography - Semiconductor Engineering
Photolithography is a patterning process in chip manufacturing. The process involves transferring a pattern from a photomask to a substrate. This is primarily done using steppers and scanners, which are equipped with optical light sources. Other forms of lithography include direct-write e-beam and nanoimprint. There are also several next-generation lithography (NGL) technologies in R&D, such

What Is a Melting Crucible? (with picture)
1/8/2020· A standard silicon carbide crucible structure would break down and contaminate the metal sample, since iron melts at 2,800 Fahrenheit (1,538 Celsius). A crucible with a graphite mixture, such as silicon carbide models have, is also not used for iron melting as the graphite dissolves in and reacts with the iron, altering its content and slowly wearing away at the crucible structure.
