Abstract:
A universal semiconductor-recipe editing system comprising:a recipe data object model (R-DOM), coupled to read and write recipe data files, each recipe data file for controlling a process performed on a wafer by a semiconductor-manufacturing machine, wherein the R-DOM includes means for reading recipe data files for a plurality of semiconductor-manufacturing machines from different vendors that require different native formats of the recipe data files, the R-DOM for locating and reading a desired parameter within a recipe data file; a visual recipe editor, coupled to the R-DOM, for displaying parameters from the recipe data file to a user, the R-DOM sending the desired parameter to the visual recipe editor for display to the user; and an R-DOM file, accessed by the R-DOM, for identifying locations of parameters in the recipe data file, the R-DOM file containing a sequence of parameters, the sequence of parameters being in a same order as a native sequence of parameters in the recipe data file; wherein the R-DOM determines the location of the desired parameter in the recipe data file, the R-DOM reading the desired parameter at the location in the recipe data file and sending the desired parameter to the visual recipe editor for display to the user, whereby the R-DOM uses the R-DOM file to locate the desired parameter in the recipe data file.
