IYM Technologies' Patent

IYM Technologies is technology develop company that has four U.S. Patents assigned to it, and has one patent application:

U.S. Patent No. 7,448,012 “Methods and System for Improving Integrated Circuit Layout:” In accordance with the present method and system for improving integrated circuit layout, a local process modification is calculated from simulated process response variables at a set of control points. Said modification values are incorporated into the layout constraints imposed by design rules and design intent to account for manufacturing friendliness. Solving the updated constraint equation with user specified objective function produces a new layout with increased manufacturability. The new layout may further contain data tags that enable optimal process correction to be performed on selected locations, leading to reduction in data size and mask complexity. Also in accordance with this invention, physical design tools are enhanced to read and process anisotropic design rules. This patent was filed on April 15, 2005 and issued on November 4, 2008. It has 18 claims, of which two are independent. For a .pdf of the ‘012 patent, click here.

U.S. Patent No. 8,176,445 “Method and System for Improving Integrated Circuit Layout:” We disclose a method for optimizing integrated circuit layout which comprises analyzing constraint relationship among objects in an initial layout; constructing local modifications to the constraint relationship; forming new constraint relationships by combining initial constraint relationships with their local modifications; and producing a new layout by implementing the new constraint relationships. Local modification to constraints provides a framework for bringing detailed local information into the design process in a highly automated manner, which can be applied to a wide range of situations. We disclose preferred embodiments on improving lithography printability, reducing defect susceptibility, and improving circuit performance such as reducing layout variability and leakage. This patent was filed on July 29, 2008 and issued on May 8, 2012. It has 20 claims, of which three are independent. For a .pdf of the ‘445 patent, click here.

U.S. Patent No. 8,266,557 “Method and System for Direction Dependent Integrated Circuit Layout:” In accordance with the present method and system for anisotropic integrated circuit layout we extract a set of anisotropic design rules for integrated circuit manufacturing systems that have directional preference. We enhance various physical design tools to read and process anisotropic design rules in order to generate anisotropic design layout that takes advantage of an anisotropic manufacturing system. A divisional of the ’012 patent, this patent was filed on July 29, 2008 and issued on September 11, 2012. It has 20 claims, of which three are independent. For a .pdf of the ‘557 patent, click here.

U.S. Patent No. 8,464,187 “Integrated Circuit Having Direction Dependent Wiring:” In accordance with the present method and system for improving integrated circuit layout, a local process modification is calculated from simulated process response variables at a set of control points. Said modification values are incorporated into the layout constraints imposed by design rules and design intent to account for manufacturing friendliness. Solving the updated constraint equation with user specified objective function produces a new layout with increased manufacturability. The new layout may further contain data tags that enable optimal process correction to be performed on selected locations, leading to reduction in data size and mask complexity. Also in accordance with this invention, physical design tools are enhanced to read and process anisotropic design rules. A continuation of the ’557 patent, this patent was filed on July 12, 2012 and issued on June 11, 2013. It has 20 claims, of which three are independent. For a .pdf of the ‘187 patent, click here.

U.S. Patent Application Number 13/886,577: This application is pending before the U.S. Patent and Trademark Office. It was filed on June 7, 2013.
