[1] | The Company noted a growing portion of the general semiconductor and LED end market is increasing in complexity and driving more capital intensity, therefore demanding more advanced packaging solutions. This has reduced the relevance of the advanced packaging end market. In view of this, sales previously defined as advanced packaging will be primarily categorized within the general semiconductor end market.
