And the lead is led out from the component packaging body. In the surface mount component, the term refers to the outer leads such as the tab lead, the J lead, and the I lead.
The semiconductor is a substance with conductivity between an insulator and a conductor, and the conductivity of the semiconductor is easy to control and can be used as an element material for information processing. Semiconductors are very important from the viewpoint of technological or economic development. The core elements of many electronic products, such as computers, mobile phones, and digital recorders, utilize the conductivity change of semiconductors to process information. Common semiconductor materials are silicon, germanium, gallium arsenide, etc., and silicon is the most influential of various semiconductor materials in commercial applications.
Materials having electrical conductivity between conductors and insulators at normal temperatures, called semiconductors, exist in various forms, solid, liquid, gas, plasma, and the like. Materials with poor or poor electrical and thermal conductivity, such as diamond, intraocular lenses, amber, ceramics, and the like, are commonly referred to as insulators. And metals with good electrical and thermal conductivity, such as gold, silver, copper, iron, tin, aluminum, etc., are called conductors. The material between the conductor and the insulator may simply be referred to as a semiconductor. The discovery of semiconductor materials was the latest compared to conductors and insulators, and the existence of semiconductors was not really accepted by academia until the 30's of the 20 th century when the purification technology of the materials was improved.
