WebApr 24, 2008 · Dry oxidation is a process in which silicon dioxide is grown from silicon in a furnace in the prescence of oxygen. In contrast, wet oxidation is performed with steam. Wet oxidation is preferred to dry oxidation for growing thick oxides, because of the higher growth rate. However, fast oxidation leaves more dangling bonds at the silicon interface, which produce quantum states for electrons and allow current to leak along the interface. (This is called a "dirty" interface.) Wet oxidation also yields a lower-density oxide, with lower dielectric strength. The long time required to grow a thick oxide in dry oxidation makes this process impractical. Thi… milly carlucci twitter
