Method, system and software for accessing design rules and library of design features while designing semiconductor device layout
First Claim
1. A non-transitory computer readable storage medium encoded with computer program code such that, when said computer program code is executed by a processor, said processor performs a semiconductor device design method, said design method comprising:
- accessing design rules by interacting with a graphical user interface (GUI) by selecting a feature of a semiconductor device layout when said semiconductor device layout is displayed on said GUI,wherein said accessing said design rules automatically accesses a library of design features, and wherein the semiconductor device layout is used to form a photomask set.

Abstract
Provided is a system and method for designing the layout of integrated circuits or other semiconductor devices while directly accessing design rules and a library of design features by interfacing with a GUI upon which the design layout is displayed. The design rules may be directly linked to the design features of the pattern library and imported into the device layout. The design rules may be directly accessed while designing the layout or while conducting a design rule check and the design features from the pattern library may be used in creating the layout.
