IEC 62258-2:2011

Overview

IEC 62258-2:2011 is an international standard developed by the International Electrotechnical Commission (IEC) that specifies the exchange data formats for semiconductor die products. It forms part 2 of the IEC 62258 series and introduces a Device Data Exchange (DDX) format designed to facilitate the transfer of detailed geometric and device information between semiconductor die manufacturers and CAD/CAE users. This standard supports the production, supply, and utilisation of diverse semiconductor die products, such as wafers, singulated bare die, dies with connection structures, and partially encapsulated devices.

IEC 62258-2:2011 outlines flexible and extensible data formats that support exchange in multiple file formats including the STEP physical file format (ISO 10303-21) and XML, ensuring interoperability across diverse design and manufacturing environments. The standard reflects version 1.3.0 of the DDX data format with updates to several parameters to improve accuracy and usability.
