SOI (Silicon On Insulator)

Silicon on Insulator (SOI) is a semiconductor technology where a thin layer of silicon is separated from the bulk silicon substrate by a layer of insulation, typically silicon dioxide. This structure reduces electrical interference and heat dissipation issues, enabling faster, more efficient, and smaller electronic devices. SOI chips are used in advanced electronics like high-speed processors and telecom equipment because they improve performance and power efficiency compared to traditional silicon wafers. Essentially, SOI creates a lightweight, isolated environment within the chip that enhances its capabilities and reliability.
