Abstract:
A method of surface treatment of materials at a downstream of a plasma source, said method comprising:generating a plasma from a Gas-C in a plasma source, said Gas-C comprising a gas-A and a gas-B, said gas-A selected from a compound comprising at least a nitrogen bearing compound or an other gas, said other gas being selected from mixtures of elements in group 18 classified in the atomic periodic table, Gas-B comprising at least a H.sub.2 O bearing compound;injecting a Gas-D downstream of said plasma source of said Gas C;setting an object downstream of the Gas-D injection and downstream of said plasma source, said object comprising a surface; andprocessing said surface of said object by a mixture species generated from said Gas-C in said plasma and said Gas-D;wherein said H.sub.2 O bearing compound in said Gas-C includes a H.sub.2 O bearing concentration that is lower than a Gas-A concentration.
