Tungsten as Contact Material
Tungsten discs and 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 suitable 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.
Applications:
Silicon Controlled Rectifiers Diodes
Transistors
Thyristors (GTO 's)
Heat Sink Bases in IC's, LSI's and Hybrid Circuits
Benefits:
CTE matched to semiconductor substrate
Good thermal conductivity
High volume production
