Fujitsu Semiconductor has continued to supply detailed support for product quality to ensure a stable supply of high-quality products.
An example is failure analysis. If any failure by our products occurs at the customer side after shipping, we investigate the failed device to find the root cause. Then we implement countermeasures against the cause, and take corrective action to prevent the same failure recurring. The failure analysis report to the customer includes the above status, the cause of failure, countermeasure, and corrective action etc. We provide feedback internally to improve quality and reliability of products. In addition, Fujitsu Semiconductor responds to customer requests such as providing of quality and reliability data, and cooperating with factory audits.
Customer Quality Support Diagram
Fujitsu Semiconductor carefully analyzes all products returned from customers as failures. After an initial check on external appearance and electrical characteristics, we investigate the cause of the failure. When we specify the root cause, we implement countermeasures against the cause, and take corrective action to prevent the same failure from recurring.
Fujitsu Semiconductor provides feedback on the failure analysis information to not only our internal engineering Dept. but also suppliers to improve the quality and reliability of the final product.
