    摘要: The present invention is directed to a method and a system for non-destructively, efficiently and accurately detecting asymmetry in the profile of a feature formed on a wafer during the process of semiconductor fabrication. The method encompasses directing a beam of light or radiation at a feature and detecting a reflected beam associated therewith. Data associated with the reflected beam is correlated with data associated with known feature profiles to ascertain profile characteristics associated with the feature of interest. Using the profile characteristics, an asymmetry of the feature is determined which is then used to generate feedback or feedforward process control data to compensate for or correct such asymmetry in subsequent processing.

    摘要: A system and method is provided that facilitates the application of a uniform layer of developer material on a photoresist material layer. The system includes a nozzle adapted to apply a predetermined volume of developer material on a photoresist material layer along a linear path having a length approximately equal to the diameter of the photoresist material layer. A movement system moves the nozzle to a first position offset from a central region of the photoresist material layer for applying a first predetermined volume of developer material to the photoresist material layer while the developer material is spin coated. The movement system also moves the nozzle to a second position offset from the central region for applying a second predetermined volume of developer material to the photoresist material layer while the developer is spin coated. The first position is located on an opposite side of the central region with respect to the second position. A method of adjusting the offset position and/or volume of developer material applied at the first and second position is also provided. The method utilizes developed photoresist material layer thickness data provided by a measurement system to adjust the offset position and/or volume of the developer.

    摘要: A system for monitoring a latent image exposed in a photo resist during semiconductor manufacture is provided. The system includes one or more light sources, each light source directing light to the latent image and/or one or more gratings exposed on one or more portions of a wafer. Light reflected from the latent image and/or the gratings is collected by a signature system, which processes the collected light. Light passing through the latent image and/or gratings may similarly be collected by the signature system, which processes the collected light. The collected light is analyzed and can be employed to generate feedback information to control the exposure. The collect light is further analyzed and can be employed to generate feed forward information that can be employed to control post exposure processes including development and baking processes.

    摘要: The present invention is directed to a system and a method for controlling a thin film formation on a moving substrate as part of a process for manufacturing an integrated circuit. The invention involves the use of scatterometry to control the thin film formation process by analyzing the thin film on the moving substrate comprising an optical indicia and a periodic analysis structure in a periodic manner. The optical indicia is spatially associated with the periodic analysis structure and is utilized in conjunction with a signaling system to determine a position of the moving substrate, whereby a repeatable analysis of a corresponding location on the moving substrate can be performed. Scatterometry permits in-situ measurements of thin film formation progress, whereby thin film formation process conditions can be controlled in a feedback loop to obtain a targeted result. Scatterometry can also be facilitated by providing a grating pattern on a non-production portion of the substrate.
