Product Description
Phi 2'' to 8'' Thermal Oxide Silicon Wafer N-Type P-Type With an Insulating Oxide Layer
BonTek provides high quality silicon thermal oxide wafers in all diameters from 2″ to 300mm. We ensure your specific requirements are met by choosing prime grade and defecting free silicon wafer as a substrate so that a high uniform layer of thermal oxide is formed in a furnace.
In micro-technology, the main insulating material used is Silicon dioxide which in chemical symbols is written as SiO2. In order to produce an insulating oxide layer, thermal oxidation, which is the most common technique used to obtain the layer is used. The process of obtaining the layer is performed in a furnace.
