Silicon on Insulator Introduction description in (Semiconductor Devices).

1. SOI Silicon on Insulator Technology

2. INTRODUCTION SILICON : Silicon is a chemical element that is present in sand and glass and which is a best known semiconductor material in electronic components. INSULATOR : A material that does not easily transmit energy such as electric current or heat .

3. WHAT IS SILICON ON INSULATOR Silicon on insulator technology refers to the use of layered silicon-insulator-silicon substrate in place of conventional silicon substrate in semiconductor manufacturing.

4. 4 Need for SOI Technology

5. SOI-based devices differ from conventional silicon-built devices in that the silicon junction is above an electrical insulator, typically silicon dioxide or sapphire SOI Technology

6. In a Silicon On Insulator (SOI) Fabrication technology , Transistors are encapsulated in SiO2 on all sides. SOI Technology

7. The choice of insulator depends largely on intended application Sapphire is used for high-performance radio frequency (RF) and radiation-sensitive applications, and Silicon dioxide is used for diminished short channel effects in microelectronics devices. SOI Technology
