    摘要: A method for reducing the dimension of a patterned organic photoresist area by reducing the pressure of a reactive environment surrounding the patterned photoresist to cause outgasing. The outgased materials CxHyOz are then decomposed in the reactive environment leaving the outgased photoresist porous. The environment surrounding the patterned photoresist is then increased to atmospheric pressure, which compresses or shrinks the porous photoresist. Photoresist lines having a dimension as small as about 0.085 μm can be obtained.

    摘要: A multi-sub-process cleaning procedure cleans phase shift photomasks and other photomasks and Mo-containing surfaces. In one embodiment, vacuum ultraviolet (VUV) light produced by an Xe2 excimer laser converts oxygen to ozone that is used in a first cleaning operation. The VUV/ozone clean may be followed by a wet SC1 chemical clean and the two-sub-process cleaning procedure reduces phase-shift loss and increases transmission. In another embodiment, the first sub-process may use other means to form a molybdenum oxide on the Mo-containing surface. In another embodiment, the multi-sub-process cleaning operation provides a wet chemical clean such as SC1 or SPM or both, followed by a further chemical or physical treatment such as ozone, baking or electrically ionized water.
