Method of fabricating a pellicle frame

A method of fabricating a lithography apparatus, the method comprising:

• preparing a main body of a pellicle frame that includes a first material layer including aluminum, the first material layer having a vent hole;
• forming a second material layer on a surface of the first material layer of the pellicle frame using a wet process using wet oxidation plasma, the second material layer including aluminum oxide and a transition metal, the second material layer being formed on the first material layer such that the first material layer is completely enclosed by the second material layer excepting a sidewall of the vent hole;
• and
• attaching a pellicle membrane to the pellicle frame having the second material layer with an adhesive layer interposed between the second material layer and the pellicle membrane.
