    摘要: The invention includes methods of converting reticles from configurations suitable for utilization with later generation (shorter wavelength) stepper radiations to configurations suitable for utilization with earlier generation (longer wavelength) stepper radiations. The invention can be utilized for converting a reticle from a configuration suitable for 193 nanometer wavelength radiation to a configuration suitable for 248 nanometer wavelength radiation. In such aspect, a quartz-containing material of a substrate can be protected with a patterned layer consisting essentially of molybdenum and silicon while the quartz-containing material is subjected to a dry etch. The configuration suitable for 248 nanometer wavelength radiation can be constructed so that a phase of 248 nanometer wavelength radiation is shifted by about 180° upon passing through combined thicknesses of the patterned layer and the quartz-containing material, relative to 248 nanometer wavelength radiation which passes only through the quartz-containing material.

    摘要: A method for removing impurities (e.g., atomic sulfur) from a reticle for use in photolithography is provided. In one embodiment, a reticle (or photomask) comprising a plate, a first layer over the plate, and a photoresist layer over the first layer is provided. The photoresist layer is removed with a first chemistry comprising a sulfur-containing compound. At least a portion of the first layer is removed with a second chemistry comprising a sulfur-containing etchant, thereby exposing portions of the plate. Removing the photoresist layer and/or at least a portion of the first layer leaves sulfur on at least portions of the reticle. In a cleaning step, the reticle is contacted with one or more excited species of oxygen to remove residual sulfur and other contaminants, such as carbon, sulfur and oxygen-containing species. Methods of embodiments can be used to clean, e.g., binary photomasks, attenuated phase shift masks (APSMs) and high transmission attenuated photomasks.

    摘要: The invention encompasses a method for forming a pattern across and expanse of photoresist. The expanse comprises a defined first region, second region and third region. The first region is exposed to a first radiation while leaving the third region not exposed; and subsequently the second region is exposed to a second radiation while leaving the third region not exposed to the second radiation. The second radiation is different from the first radiation. The exposure of the first and second regions in a solvent relative to the solubility of the third region of the expanse. After the first and second regions of the expanse are exposed to the first and second radiations, the expanse is exposed to a solvent to pattern the expanse. The invention can be utilized in forming radiation-patterning tools and stencils; and in patterning semiconductor substrates.
