More info

Molybdenum Squares includes pure molybdenum Squares and coated molybdenum. Coated molybdenum Squares is PVD or evaporation with Ruthenium (Ru), Rhodium (Rh), Nickel (Ni), Silver (Ag), Gold (Au), etc. Molybdenum Squares are widely used as contact materials in silicon-controlled rectifier diodes, transistors, and thyristors. Molybdenum has similar coefficients of thermal expansion (CTE) to silicon combined with moderate thermal conductivity and is therefore appropriate for large area power devices where considerable heat is generated. Additional applications include the utilization of molybdenum as heat sink bases in IC’s, LSI’s, and hybrid circuits.
