VISHAY - one of the world's largest manufacturers of discrete semiconductors and passive components

Vishay Semiconductor Itzehoe GmbH is part of the business division of Vishay Siliconix and produces so-called PowerMOS transistors. These are special power transistors which are required in computers, mobile phones, automobiles, fixed network telecommunications, and in many other applications in industry electronics. The semiconductor factory in Itzehoe employs approx. 185 staff members and produces ca. 150,000 silicon wafers (150 mm in diameter) per year.


The corporate group Vishay Intertechnology, Inc. located in Malvern, Pennsylvania/USA is one of the world's largest manufacturers of discrete semiconductor components (diodes, rectifiers, transistors, optoelectronic elements) and passive electronic parts (resistors, condensers, inductivities and transformers). These are used in a great number of electronic products. Vishay owns production sites in 17 countries and has over 27,000 employees worldwide.


Vishay Intertechnology has decided to invest around 60 million US-Dollars until 2007 into expanding their production line for microchips, including the necessary infrastructure, in Itzehoe. Vishay thus underlines the importance of the location Itzehoe for the international corporate group. As part of this expansion additional qualified jobs will be created when working to capacity, so that the number of employees in Itzehoe will increase from currently 185 to 230. In the maximum expansion stage, the production capacity for microchips will almost double that of today.


An important step is the conversion of the entire production line for the processing of silicon wafers of 200 mm diameter. Currently, only wafers of 150 mm diameter are being processed in the state-of-the-art dust free room in Itzehoe. The conversion will be accompanied by a technological leap to even higher integrated PowerMOS transistors. The low activation resistance of these transistors, resulting from the integration density, will facilitate low-loss operations and thus save power and resources.
