Therefore, the difference between photoresist and chip: photoresist is one of the key materials for micro graphics processing in microelectronics technology, especially in recent years, the development of large-scale and very large scale integrated circuits has greatly promoted the research and development and application of photoresist. The printing industry is another important area of photoresist application. Chip: A semiconductor device that is etched and wired on a semiconductor sheet to achieve a certain function. Not only silicon chips, common also include gallium arsenide (gallium arsenide is toxic, so some inferior circuit boards do not be curious to decompose it), germanium and other semiconductor materials.
