Appl. No.:

12/695530

Assignee:

Synopsys, Inc. - Mountain View CA

International Classification:

G06F 17/50

US Classification:

716 55, 716 54, 716 56

Abstract:

One embodiment of the present invention relates to a system that calibrates a photolithography process model. During operation, the system receives a process model which models a photolithography process. The system further receives measured critical dimension (CD) values for a first set of features that were printed by applying the photolithography process to a layout. The system then calibrates the process model using the measured CD values so that CD values predicted by the process model substantially match the measured CD values, and depth of focus (DOF) values predicted by the process model for a second set of features are substantially maximized.

Abstract:

Methods and systems for enhancement of device accessibility are described. In an example, an operating system configured to be executed on a device, may be configured to support a plurality of software applications and to support a plurality of modes of operation of the device. A given software application may include a user-interface comprising a user-interface item having a text in a first language. The operating system may be configured to receive a selection of the user-interface item of the given software application. Based on the operating system being in an accessibility mode common to the plurality of software applications, the operating system may be configured to determine a translation of the text into a second language; and a voice output corresponding to a spoken utterance of the translation of the text. The operating system further may be configured to provide, by the device, the voice output.

International Classification:

G06F 17/50

US Classification:

716 51, 716 54

Abstract:

A method of calibrating a compact model for a lithographic process is described. In this method, the nominal compact model can be provided. Notably, an input energy effect can be separated from chemical effects and other factors regarding the photoresist. Using a processor, the compact model can be calibrated based on the input energy, thereby generating an energy-sensitive compact model. The energy-sensitive compact model can quickly construct 3D resist profiles capturing resist profile degradation at any horizontal plane. Because this method does not change any form of compact modeling, it can be integrated as is into validation and correction processes. In other embodiments, the energy-sensitive compact model can be further calibrated based on one or more of the chemical effects and/or other factors.

International Classification:

G06F 16/9535
G06F 3/0482
G06F 16/906
G06F 16/9538
G06F 40/30

Abstract:

A description-based search system can generate descriptions from item properties (e.g., item attribute) combinations. A user search request can be matched to one or more closest matching descriptions. The matching descriptions can be submitted as a query to a datastore, which returns results for display to the user. Additionally, the description based search system can link selected descriptions to pre-linked one or more pre-linked results.
