The role of process simulation is becoming an increasingly important part of microlithography process control and photomask metrology as wafer feature sizes become smaller than the exposure wavelength, because the pattern transfer from photomask to wafer is nonlinear. An important factor hindering the increased use of simulation applications, however, is their inclination to be standalone applications not easily integrated into the overall process. These observations have led to the concept of The Neolithography Consortium. This group is being formed for the purpose of identifying impediments to the integration of simulation and metrology tools into the microlithography process, and finding solutions to remove those impediments. It is comprised mainly of companies who create or use commercial IC microlithography simulation software, or who produce metrology or production tools which interface with simulation software, and their customers. Membership is open to all interested parties.
