Tungsten disc and tungsten squares are widely used as contact materials in silicon controlled rectifier diodes, transistors and thyristors. Tungsten has similar coefficients of thermal expansion (CTE) to silicon combined with moderate thermal conductivity, and are therefore appropriate for large area power devices where considerable heat is generated. Further applications include the use of Tungsten as heat sink bases in IC’s, LSI’s and hybrid circuits.
