floatzoneteknik

Floatzoneteknik, also known as float zone refining, is a method used to produce high-purity single crystals of semiconductors. This technique is particularly valuable for materials like silicon, which is essential for the production of electronic devices. The process involves melting a polycrystalline semiconductor rod and passing it through a high-temperature, low-pressure zone. This zone is created by heating with an induction coil or a radio frequency (RF) coil. As the molten zone moves along the rod, impurities are rejected from the solidifying crystal, resulting in a highly purified single crystal. The float zone technique is advantageous because it can produce crystals with very low defect densities, making them ideal for applications in high-performance electronics. The method is also versatile and can be adapted for various types of semiconductors, making it a widely used technique in the semiconductor industry.
