Integrated circuits, Micro LEDs, VCSEL… To produce the mentioned and many more technologies, manufacturers have a high demand for high-purity Arsenic or components made from it.
Since these technologies are settled or future-oriented and the market of communications and information enjoys strong growth, demand is expected to rise beyond the current market level.
In addition to the positive growth forecasts regarding the high-purity arsenic market, another segment of PPM Pure Metals GmbH gives cause for delight. High-purity antimony, which is mainly used in compound semiconductors and as a dopant, is facing strong demand.
In particular, the dopant market, which is essentially based on the production of silicon single crystals, is undergoing strong growth. In turn, the cultured crystals are used to produce special wafers that serve as a substrate for electronic components or components for photovoltaic systems.
In this context, it is important to understand what a dopant is used for. High purity arsenic and high purity antimony – high purity stands for 7N quality (99.99999%) or better – is specifically used to change the electrical conductivity of common silicon semiconductor devices.
