    摘要: Architecture for monitoring a bottom anti-reflective coating (BARC) undercut and residual portions thereof during a development stage using scatterometry. The scatterometry system monitors for BARC undercut and residual BARC material, and if detected, controls the process to minimize such effects in subsequent wafers. If one or more of such effects has exceeded a predetermined limit, the wafer is rerouted for further processing, which can include rework, etch back of the affected layer, or rejection of the wafer, for example.

    摘要: A system for selectively generating and feeding forward reticle fabrication data is provided. The system includes components for fabricating a reticle and a control system operatively connected to the fabricating components, where the control system can control the operation of the fabricating components. The control system bases its control of the fabricating components, at least in part, on feed forward control information generated by a processor that analyzes scatterometry based reticle fabrication data gathered from measurement components. The scatterometry data is compared to data stored in a signature data store that facilitates analyzing gathered scatterometry signatures to produce feed forward control information that can be employed to manipulate subsequent reticle fabrication processes and/or apparatus.

    摘要: A system and methodology are disclosed for monitoring and controlling a semiconductor fabrication process. Measurements are taken in accordance with scatterometry based techniques of repeating in circuit structures that evolve on a wafer as the wafer undergoes the fabrication process. The measurements can be employed to generate feed forward and/or feedback control data that can utilized to selectively adjust one or more fabrication components and/or operating parameters associated therewith to adapt the fabrication process. Additionally, the measurements can be employed in determining whether to discard the wafer or portions thereof based on a cost benefit analysis, for example. Directly measuring in circuit structures mitigates sacrificing valuable chip real estate as test grating structures may not need to be formed within the wafer, and also facilitates control over the elements that actually affect resulting chip performance.

    摘要: A system comprised of a plurality of fabs that are operatively coupled and share data from a common framework for correlating production. The fabs can be coupled via Internet, cellular, optical, landline, microwave and satellite communication means and the like. Data can be transferred to and/or received from a central, integrated correlating entity or from several distributed correlating entities. The fabs send and receive correlating data that relates to production information such as tolerances, critical dimensions, geometry and the like. The correlating entity(s) has the capability to increase production by performing probabilistic computations on the received correlating data and utilizing the resulting information to maintain correlating parameters at remote locations. The computations performed can include such calculations as Bayesian inferencing and the like. The system inherently precludes the necessity for physically transporting parametric test entities between different fab or tooling locations.
