摘要： The present invention provides a system and methodology for dummy-dispensing resist though a dispense head while mitigating waste associated with the dummy-dispense process. The dummy dispensed resist is returned to a reservoir from which it was taken. Between substrate applications, the dispense head can be positioned to dispense resist into a return line. The flow of resist from the dispense head keeps resist from drying at the dispense head. By funneling the dummy-dispensed resist into a return line with low volume, for example, waste from the dummy-dispensing process can be mitigated.

摘要： A system and method for detecting bubbles in a lithographic immersion medium and for controlling a lithographic process based at least in part on the detection of bubbles is provided. A bubble monitoring component emits an incident beam that passes through the immersion medium and is incident upon a substrate to produce a reflected and/or diffracted beam(s). The reflected and/or diffracted beam(s) is received by one or more optical detectors. The presence or absence of bubbles can be derived from information extracted by scatterometry from the reflected and/or diffracted beams. A process control component interacts with a positioning component and an optical exposure component to alter a lithographic process based at least in part on the results of the scatterometry.

摘要： The invention provides systems and processes that form the inverse (photographic negative) of a patterned first coating. The patterned first coating is usually provided by a resist. After the first coating is patterned, a coating of a second material is provided thereover. The uppermost layer of the second coating is removed, where appropriate, to expose the patterned first coating. The patterned first coating is subsequently removed, leaving the second coating material in the form of a pattern that is the inverse pattern of the first coating pattern. The process may be repeated with a third coating material to reproduce the pattern of the first coating in a different material. Prior to applying the second coating, the patterned first coating may be trimmed by etching, thereby reducing the feature size and producing sublithographic features. In addition to providing sublithographic features, the invention gives a simple, efficient, and high fidelity method of obtaining inverse coating patterns.

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.
