The molybdenum disc, also known as molybdenum base plate, molybdenum substrate, features excellent electric and thermal conductivity, lower thermal expansion coefficient, higher bending strength, and so on.
With their high purity as well as high electrical and thermal conductivity, our materials reliably dissipate heat away from the active device. An ideal coefficient of thermal expansion matching the semiconductor material avoids critical mechanical stresses.
Application
Molybdenum discs are widely used as contact materials in silicon controlled rectifiers' diodes, transistors and thyristors (GTO'S). Due to its lower cost and weight, molybdenum substrates are now accepted as the first choice for power semiconductor devices other than in specialist applications.
