ABSTRACT

Circuit designs and IC processing techniques become more complex every day. As a result the scope of manufacturing data required for analysis becomes larger and more critical. In order to handle the wealth of information, from a plethora of sources, many data warehousing concepts must be utilised. These include both data warehouses and data marts for all aspects of the manufacturing process. Sources of data for the circuit owner, quite often a Fabless entity, must include the wafer manufacturer, the IC manufacturer and the assembly shop. Currently all this information must also be fully Web-enabled. This allows the entire supply chain complete and confidential access to the information. The concepts and requirements of a data mart are discussed in this article as well as some tools that assist in the data analysis process.
