摘要:
A method for fabricating a step-formed patterned layer is provided. First, a first patterned photo-resist dry film is formed on a first material layer. Next, a second material layer is formed on the first material layer and covers the first patterned photo-resist dry film. A second patterned photo-resist dry film is then formed on a second material layer, and the patterns of the first patterned photo-resist dry film and the second patterned photo-resist dry film are different and the second patterned photo-resist dry film further exposes the second material layer over the first patterned photo-resist dry film. Subsequently, the first material layer and the second material layer are partially removed by using the first patterned photo-resist dry film and the second patterned photo-resist dry film as a mask. The first patterned photo-resist dry film and the second patterned photo-resist dry film are then removed.
