摘要： A system and method is provided for determining and controlling development of a semiconductor substrate employing fluorescence spectroscopy. One aspect of the invention relates to a system and method employing fluorescence spectroscopy to facilitate control of a chemical trim etch process during development of a photoresist material layer. The chemical trim etch process comprises applying a trim compound or material to a patterned photoresist. The trim compound or material is diffusable into the sides and top of the patterned resist. The diffused regions of the resist are soluble in a developer, which facilitates creating smaller features in the patterned photoresist. The fluorescence spectroscopy system can be employed to measure isolated and dense gratings or CDs and use the evolution of the CD to determine when to terminate the chemical trim process.

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.

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： A system for characterizing a chemical mechanical polishing process is provided. The system includes a wafer that has a metal, polysilicon, and/or dielectric layer and/or substrate and a temperature sensor located in and/or on the metal, polysilicon and/or dielectric layer and/or substrate. The system also includes a temperature monitoring system that can read the wafer temperature from the temperature sensors and that can analyze the wafer temperature to characterize the chemical mechanical polishing process. Such characterization includes producing information concerning relationships between wafer temperature and polishing rate, polishing uniformity and introduction of defects during polishing. Such relationships are correlated with wafer temperature as related to parameters like polishing time, pressure, speed, slurry properties and wafer/metal layer properties. Such characterization can be employed, for example, to better understand a CMP process, to facilitate initializing subsequent chemical mechanical polishing processes and/or apparatus and/or to control such chemical mechanical polishing processes and/or apparatus by monitoring and/or controlling wafer temperature.
