Thermal Oxide Wafer, higher uniformity, and higher dielectric strength , excellent dielectric layer as an insulator


Thermal oxide or silicon dioxide layer is formed on bare silicon surface at elevated temperature in the presence of an oxidant , the process is called thermal oxidation. Thermal oxide is normally grown in a horizontal tube furnace , at temperature range from 900°C ~ 1200°C , using either a "Wet" or "Dry" growth method . Thermal oxide is a kind of "grown" oxide layer , compared to CVD deposited oxide layer , it has a higher uniformity, and higher dielectric strength , it is an excellent dielectric layer as an insulator . In most silicon- based devices, thermal oxide layer play an important role to pacify the silicon surface to act as doping barriers and as surface dielectrics . we provides thermal oxide wafer in diameter from 2" to 12 " , we always choose prime grade and defect free silicon wafer as substrate for growing high uniformity thermal oxide layer to meet your specific requirements . Contact us for further information on price & delivery time .


Thermal Oxide Capability

Typically after thermal oxidation process , both front side and back side of silicon wafer have oxide layer . In case only one side oxide layer is required , we can remove back oxide and offer one side thermal oxide wafer for you .
