Characteristics of Gold Wire Bonds with Ti- and Ni-Based Contact Metallization to n-SiC for High Temperature Applications

Abstract:

Article Preview

The stability of Au wire connections to n-SiC/Ti ohmic contacts and to n-SiC/Ni ohmic contacts with top Au or Pt layers has been investigated. Long-term tests of the connections are performed in air at 400oC. Evaluation of electrical parameters, morphology and structure of the metallization as well as the strength of Au joint show stable Au wire bonds to the metallization with Ti-ohmic contacts.
