[. . . ] CAD E N C E M A S K C O M P O S E R ET I C LE AND WAFE R SY N T H E S I S S U I T E DATASHEET CADENCE MASKCOMPOSE SUITE Within the Cadence MaskCompose suite, technology-and fab-specific requirements for the tapeout flow are captured by appropriate specialists at high levels of abstraction using a "definition module" GUI. Once captured, this flow definition information can be used over and over again by "implementation modules" to automatically generate appropriate circuit-specific output data. [. . . ] After entering a few simple pieces of information, the program is executed and generates the reticle design and associated wafer layout in conformance with the requirements set forth in the definition module.

Floorplan definitions may be created and controlled byphotomasking/lithographyorCAD specialists while actual design-specific implementations can be handled in the design group by the layout specialist. layer polarities andmin/maxscribesizes. Includeditems may be defined as required vs. Scribe sizes may be specified in terms of a minimum size, maximum size, and an increment value by which the scribe size is increased until all required features are placed or maximum size is reached. Definitions may be constrained to allow for various types of equipment mix and match(forexample, 1x/5xmixesor stepper vendor combinations). Interactive wafer module The user also has the ability to manually manipulate and control the wafer layout or stepping patterns. The interactive wafer module provides the following user controls: · Addordropexposures(shots) · Add, delete, move, copy, andplace drop-in(s) · Modifyorintroducerowand column shifting · Markadditionalnon-yieldingdie archive documentation, can be generated. Because information is extracted directly from the MaskCompose database, content consistency is assured. As an option, documents can include automatically generated postscript and pdf diagrams of generated frame data. Information that is not captured or generated by MaskCompose can be extracted from files or prompted for at runtime by embedding appropriate commands in the various templates used. Based on the directions in a template, text entry fields, option menus, or other appropriate interface components will appear in the user's screen at runtime to prompt for and to collect the relevant information needed to generate the desired documents.
