    摘要: A method to provide a ground point for second, or subsequent, e-beam mask-writing steps by selectively removing the photoresist edge bead of a photomask substrate to expose the underlying chrome layer. The selective removal leaves at least one tab of photoresist edge bead over the chrome layer. After the first e-beam mask writing step and subsequent etch, the tab can be removed to expose a portion of the chromium layer that can act as a new ground point for a second e-beam etch. Also, a nozzle for use in selectively removing the edge bead to leave a tab of photoresist edge bead.

    摘要: A device for wet processing of a semiconductor-containing substrate addresses contamination in the wet process by removing undesired sources of gas contamination. The method involves pumping a processing liquid through a degasifier, exposing the semiconductor wafer, in a vessel, to the degasified processing liquid; and optionally recirculating the processing liquid through the degasifier and back into the vessel.

    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.
