Abstract:
1. A system for feeding forward reticle fabrication data, comprising: one or more fabricating components adapted to perform one or more reticle fabrication processes; a control system operatively connected to at least one of the one or more fabricating components, the control system adapted to control, at least in part, the operation of at least one of the one or more fabricating components and to map a reticle into a grid pattern consisting of a plurality of grid blocks; one or more measurement components operatively connected to the control system, the one or more measurement components adapted to measure, via scatterometry, one or more reticle fabrication parameters from one or more reticle fabrication processes at one or more grid blocks; and a signature data store operatively connected to the control system, the signature data store adapted to store one or more scatterometry signatures, each signature containing data for one or more grid blocks.
