  • Patent number: 8755927
    Abstract: A substrate having a plurality of zones is polished and spectra are measured. For each zone, a first linear function fits a sequence of index values associated with reference spectra that best match the measured spectra. A projected time at which a reference zone will reach the target index value is determined based on the first linear function, and for at least one adjustable zone, a polishing parameter adjustment is calculated such that the adjustable zone has closer to the target index at the projected time than without such adjustment. The adjustment is calculated based on a feedback error calculated for a previous substrate. The feedback error for a subsequent substrate is calculated based on a second linear function that fits a sequence of index values associated with reference spectra that best match spectra measured after the polishing parameter is adjusted.

  • Publication number: 20140106574
    Abstract: Provided herein are methods and apparatus for filling one or more gaps on a semiconductor substrate. The disclosed embodiments are especially useful for forming seam-free, void-free fill in both narrow and wide features. The methods may be performed without any intervening etching operations to achieve a single step deposition. In various implementations, a first operation is performed using a novel PEALD fill mechanism to fill narrow gaps and line wide gaps. A second operation may be performed using PECVD methods to continue filling the wide gaps.

  • Publication number: 20140052436
    Abstract: Described herein are systems and methods for identifying the similarity between language characters. As described herein, a pair of language characters is received at a language character match engine. The language character match engine is adapted to receive encoding configuration information from each of a plurality of encoding components, and is adapted to encode the pair of language characters based on the unique structure of each language character to generate a pair of string identification characters for each encoding component. Thereafter, each pair of string identification characters is compared to one another to generate a similarity score, and the similarity score for each pair of string identification characters is combined to create a composite similarity score. The composite similarity score represents a similarity between the pair of language characters, and is used to identify the similarity between the pair of language characters.

  • Publication number: 20130288571
    Abstract: During polishing of a substrate at a first platen and prior to a first time, a first sequence of values is obtained for a first zone of the first substrate and a second sequence of values is obtained for a different second zone of the substrate with an in-situ monitoring system. A first function is fit to a portion of the first sequence of values obtained prior to the first time, and a second function is fit to a portion of the second sequence of values obtained prior to the second time. At least one polishing parameter is adjusted based on the first fitted function and the second fitted function so as to reduce an expected difference between the zones. A second substrate is polished on the first platen using an adjusted polishing parameter calculated based on the first fitted function and the second fitted function.

    Abstract: A method of determining a physical property of a substrate includes recording a first spectrum obtained from a substrate, the first spectrum being obtained during a polishing process that alters a physical property of the substrate. The method includes identifying, in a database, at least one of several previously recorded spectra that is similar to the recorded first spectrum. Each of the spectra in the database has a physical property value associated therewith. The method includes generating a signal indicating that a first value of the physical property is associated with the first spectrum, the first value being determined using the physical property value associated with the identified previously recorded spectrum in the database. A system for determining a physical property of a substrate includes a polishing machine, an endpoint determining module, and a database.
