High-Quality TEOS Oxide Wafers for Advanced Research
TEOS oxide wafers are widely used throughout the semiconductor industry because they provide highly uniform silicon dioxide (SiO2) dielectric films with excellent electrical insulation and conformal coverage. Deposited using tetraethyl orthosilicate (TEOS) during chemical vapor deposition (CVD), these oxide layers are ideal for integrated circuits, MEMS devices, photonics, sensors, and advanced microelectronics research. UniversityWafer supplies premium TEOS-coated wafers manufactured to meet the demanding requirements of universities, research laboratories, and commercial semiconductor manufacturers.
Our TEOS oxide wafers are available with custom oxide thicknesses on a variety of substrates including silicon, silicon-on-insulator (SOI), quartz, fused silica, and other specialty materials. Films can be deposited using either PECVD or LPCVD processes depending on your application's electrical, mechanical, and thermal requirements.

What Is a TEOS Oxide Wafer?
A TEOS oxide wafer is a silicon wafer coated with a thin film of silicon dioxide (SiO2) deposited using tetraethyl orthosilicate (TEOS) as the silicon precursor during chemical vapor deposition (CVD). TEOS oxide films are widely used because they provide excellent step coverage, uniform thickness, high dielectric strength, and reliable insulation between conductive layers. These characteristics make TEOS oxide one of the most commonly used dielectric materials in semiconductor manufacturing and MEMS fabrication.
Depending on the application, TEOS films are deposited using either Plasma-Enhanced Chemical Vapor Deposition (PECVD) for lower-temperature processing or Low-Pressure Chemical Vapor Deposition (LPCVD) when higher film density and superior electrical properties are required.
Common TEOS Oxide Applications
| Application | Purpose |
|---|---|
| Shallow Trench Isolation (STI) | Electrically isolates neighboring semiconductor devices on integrated circuits. |
| MEMS Fabrication | Serves as sacrificial layers and electrical insulation in MEMS structures. |
| Interlayer Dielectric (ILD) | Separates multiple metal interconnect layers within semiconductor devices. |
| Planarization & CMP | Provides uniform oxide films before chemical mechanical polishing. |
| Photonics & Sensors | Creates insulating and optical layers for integrated photonic and sensing devices. |
