High operating temperatures and wide band gaps: our components for the compound semiconductor industry
Because of their properties, compound semiconductors represent a special challenge in manufacturing. That's why in the past they were only used for extreme and marginal applications. Meanwhile, they are now finding their place in our everyday lives. Whether LEDs, laser diodes, or power semiconductors, they now form the functional foundation for computers, telephones, and tablets, cars, televisions, and networks. Compound semiconductors therefore make an essential contribution to our modern lives: they help us to transmit energy, perform calculations, or to get from one place to another.

Our molybdenum and tungsten materials as well as their alloys are essential for the manufacturing of many compound semiconductor elements. Our metals are used in most of the major compound semiconductor production facilities worldwide. We supply components for the daily operation of your facilities and for the development of next-generation process tools. Our products cover the range of compound semiconductor front end process tools. From MOCVD layers to etching and trimming, ion milling, deposition and coating, all of our products have one thing in common – they meet the highest quality standards.

With 100 years of experience in powder metallurgical manufacturing processes and decades of experience in the semiconductor industry, you can count on us as a capable and reliable partner. Our materials scientists and engineers will work together with you to find innovative and customized solutions for your application.

From powder to the final product
Our production chain starts with the reduction of ultrapure oxide to metal powder. This is the only way that we can guarantee the high material purity of our products. We manufacture compact, metal parts from porous powder blanks. Using special forming processes and mechanical processing steps as well as modern coating and connection technologies, we turn these into complex components with the highest density and quality. At the same time, our investment in mines in the West helps to ensure a secure supply of raw materials. You also benefit from our in-house production as well as our international manufacturing network, meaning delivery capability is guaranteed.

High purity: products for displays
The highest requirements must be fulfilled so that each pixel on every display shines in its full brilliance. This is not a problem for our materials. We supply products made from molybdenum and tungsten as well as their alloys, which are essential for display production. Our products are used for the manufacturing of the glass and semiconductors right through to the coating of the displays.

They are characterized by the highest quality, best material purity, and the highest density. In this way, they help to ensure the reliable and stable operation of essential processes as well as the high-quality results of these modern displays, which guarantees cost efficiency.

We know the requirements for display manufacturing very well. Therefore, our materials scientists and engineers will work very closely with you to adapt the material properties and tolerances of our products exactly to your requirements. With us, you can rely on a reliable and sustainable partner. We are making continual investments in the latest fully automatic systems to guarantee high production capacities, reproducible process quality, and a reliable delivery capability. And this has been true for one hundred years.
