Vienna / Avezzano, May 2008 - Micron, one of the world’s largest semiconductor manufacturers, successfully uses Viscovery SOMine for clustering of spatial failure patterns.
The industrial manufacture of integrated circuits is a complex and costly process. Continuous high-quality output and high yields are essential for successful production. Product defects, therefore, need to be detected at an early stage of the production process. Defect patterns on wafers are an important source of information for the identification of production problems.
An important step is to isolate clusters of similar failure patterns and assign individual defects to distinct failure classes. Using Viscovery SOMine, Micron obtained very good results in clustering shading patterns of failing wafers.
Traditionally, defect recognition is performed by yield analysis engineers who inspect the electrical failure map of each wafer. This manual approach is not only time consuming and expensive, but also leads to high levels of misidentification; thus, Micron aims to develop systems for automatic defect recognition.
