Metals needed for semiconductors
WebFollow Other metals like aluminum and tungsten are also used for their specific properties, and the amount of each metal used can vary depending on the design of the chip. Gold is sometimes used as well, but it's generally more expensive and not as widely available as other metals. Reply 4 years ago Follow [1] What rare metals are used in chips? WebAnd with an increased demand for sustainable alternatives and efficient technologies, these metals are being reinvestigated to meet today’s semiconductor needs. For example, gallium materials are increasingly being utilised in compound semiconductors, such as gallium arsenide and gallium nitride.
