Companies want to ensure that their suppliers remain able to deliver even under extreme conditions. The severe earthquake in Japan in 2011 and the subsequent nuclear disaster at Fuku­shima sensitized the semiconductor industry to this issue, in particular. As a result, Siltronic customers have frequently inspected the division’s crisis management over recent years – for example, Fujitsu in 2014. The Japanese electronics giant scrutinized management (emergency plan to maintain delivery capacity, suppliers and communications) and continuity (manufacturing, materials and supplies, utilities, personnel, and IT systems) at the Burghausen, Freiberg and Singapore sites. Conclusion: Fujitsu rates Siltronic well above the average in all individual categories. The result can equally be applied to evaluation by other companies: customers such as Intel, Texas Instruments and Analog Devices use similar rating criteria for this type of supplier evaluation.
