|
|
||||||
|
Market Overview
|
||||||
|
|
||||||
|
The global SOI market was valued at approximately USD 1.5 billion in 2023, and is projected to grow to USD 4.8 billion by 2032, registering a compound annual growth rate (CAGR) of around 13.8% during the forecast period. The growth is driven by rising demand in consumer electronics, automotive, telecommunications, and industrial applications.

What is Silicon-on-Insulator (SOI)?
|
||||||
|
|
||||||
|
SOI technology involves the use of a layered silicon-insulator-silicon substrate instead of conventional bulk silicon. The insulator—typically silicon dioxide—reduces parasitic device capacitance, improving performance, lowering power consumption, and enhancing radiation hardness, especially beneficial for high-frequency and harsh-environment applications.
