Abstract: Methods and systems for providing a network graphical representation of database records. Database records of a record class can be selected according to descriptive criteria. An attribute of the record class can be identified from different data sources, and a network node can be associated to an instance of the attribute from the database records. The network node can be connected with a network link that designates the network node and comprises a common instance of the attribute, wherein the network link can be based on a co-occurrence of attribute values. Additional network nodes can be connected to other network nodes with network links that designate associations between the network nodes. The database records can be visualized using network nodes and network links.

Abstract: Methods for Providing a Network Graphical Representation of Database Records. Database records are selected according to descriptive criteria, wherein each of the database records are members of a common record class. Attributes of the common record class and identified and network nodes are associated to instances of the attributes from the database records. The network nodes are connected with network links that designate network nodes having common instances of the attributes such that the network nodes have a one-to-many relationship with the network links. The identifying and connecting steps are iteratively executed while modifying the descriptive criteria to change the selected database records.

Abstract: A method and apparatus for selecting and converting database records or sets of related documents into network data and presenting that data in a network visualization system that enables users to select among, and move between various network displays by selecting one or more attributes of the data to be represented as the nodes and links of the network.

Abstract: A method includes accessing a structure model defining a cross-sectional profile of a structure on a sample. The cross-sectional profile is at least partially defined using a set of blocks. Each of the blocks includes a number of vertices. One or more of the vertices are expressed using one or more algebraic relationships between a number of parameters corresponding to the structure. Information is evaluated from the structure model to produce expected metrology data for a scatterometry-based optical metrology. The expected metrology data is suitable for use for determining one or more of the number of parameters corresponding to the structure. Apparatus are also disclosed.

Abstract: The ellipsometer and method involve directing polarized light for interaction with an optical system under study at different angles of incidence from a single beam of light and detecting the light interacted with the optical system by reflection and/or transmission for each of a plurality of different angles of incidence. The simultaneous illumination of the optical system under study at a whole range of angles of incidence from a single beam of light and the collection a large multiplicity of data from the different angles detected can be accomplished rapidly and easily and with accuracy without scanning and with only one ellipsometer. A lens is used to focus the incoming light to provide the range of different angles of incidence. The range of angles is at least one or two degrees and preferably thirty degrees or more. A second lens refocuses the interacted light to a linear, multi-element detector array which extends in the plane of the incidence.
