Molybdenum Disc
Molybdenum disks are widely used as contact material in thyristor rectifier diodes, transistors and thyristors (GTO'S).
Description
Nowadays, molybdenum is the material of choice for mounting materials in power semiconductor devices, except for some special applications, due to its very low cost and light weight. Both materials, i.e. silicon and molybdenum, have the same coefficient of expansion and both have high thermal conductivity, which makes them highly desirable, especially for large-area power devices that generate a lot of heat. Further applications include the use of molybdenum as a heat sink base for semiconductor component products, large-scale integrated circuits, and hybrid circuits.

GNEE specializes in producing high purity molybdenum wafers with the highest possible density and smallest possible average grain size for semiconductor, chemical vapor deposition (CVD) and physical vapor deposition (PVD) display and optical applications. Our standard wafer sizes range from 1 inch to 8 inches in diameter and from 2 mm to 1/2 inch thick. We can also provide discs outside of this range. We produce materials using crystallization, solid-state and other ultra-high purification processes such as sublimation.
