The present invention provides a method for treating a surface of an object using, for example, a downstream region of a plasma source. The method includes a step of generating a plasma from a gas-C in a plasma source, where the gas-C includes a gas-A and a gas-B. Gas-A is selected from a compound comprising at least a nitrogen bearing compound or an other gas. The other gas is selected from a mixture of an element in group 18 classified in the atomic periodic table. Gas-B includes at least a NH3 bearing compound. The method also includes a step of injecting a gas-D downstream of the plasma source of the gas-C. The method also includes a step of setting an object (having a surface) downstream of the gas-D injection and downstream of the plasma source. A step of processing the surface of the object by a mixture species generated from the gas-C in the plasma and the gas-D is included. The NH3 bearing compound in the gas-C includes a NH3 bearing concentration that is lower than an explosion limit of NH3, which is safer than conventional techniques.
