[0002] Semiconductor is an electronic material with properties between those of conductors and insulators. Its conductivity is between that of metals (good conductors) and non - metals (insulators). Semiconductors play a crucial role in modern electronic technology.

These tiny particles and vapors may contain toxic substances such as tin oxide and other metal compounds. Prolonged inhalation of tin fumes can affect human health, potentially causing symptoms such as respiratory discomfort, headache, and fatigue, thus affecting processing safety.
