    摘要: We have reduced the critical dimension bias for reticle fabrication. Pattern transfer to the radiation-blocking layer of the reticle substrate essentially depends upon use of a hard mask to which the pattern is transferred from a photoresist. The photoresist pull back which occurs during pattern transfer to the hard mask is minimalized. In addition, a hard mask material having anti-reflective properties which are matched to the reflective characteristics of the radiation-blocking layer enables a reduction in critical dimension size and an improvement in the pattern feature integrity in the hard mask itself. An anti-reflective hard mask layer left on the radiation-blocking layer provides functionality when the reticle is used in a semiconductor device manufacturing process.

    摘要: Methods and apparatus for controlling the critical dimensions and monitoring the phase shift angles of photomasks. Critical dimensions measurement data before wafer processing and after wafer processing are collected by an integrated metrology tool to adjust the process recipe, to determine if the critical dimensions are in specification and to determine if additional etching is required. Phase shift angle and uniformity across substrate measurement after wafer processing are collected by an integrated metrology tool to determine if the phase shift angle and its uniformity are in specification. The real time process recipe adjustment and determination if additional etching is requires allow tightening of the process control. The phase shift angle and uniformity monitoring allows in-line screening of phase shift photomasks.

    摘要: Method and apparatus for etching a metal layer disposed on a substrate, such as a photolithographic reticle, are provided. In one aspect, a method is provided for processing a substrate including positioning a substrate having a metal layer disposed on an optically transparent material in a processing chamber, introducing a processing gas processing gas comprising an oxygen containing gas, a chlorine containing gas, and a chlorine-free halogen containing gas, and optionally, an inert gas, into the processing chamber, generating a plasma of the processing gas in the processing chamber, and etching exposed portions of the metal layer disposed on the substrate.
