Abstract:
A method for treating a surface of a semiconductor, whereby the surface is made by first molecules of the semiconductor with external bonds and the bonds are saturated with hydrogen atoms, wherein the method comprises the steps of:generating positive ions each having at least three positive charges with low energy with respect to the MeV, sending under vacuum a beam made of the ions toward at least one zone of the surface, whereas the at least one zone covers a determined portion of the surface, applying to the beam a deceleration voltage close to the surface, in order to give the ions of the beam a controlled average speed, whereas the ions extract electrons of the first molecules of the at least one zone without contacting the surface, so that the first molecules lose their hydrogen atoms and that the corresponding external bonds become pendant, and sending toward the at least one zone a product saturating the pendant external bonds in order to form second molecules of an insulating compound.
