Title: Metallisation of aluminium nitride ceramic - involves ceramic treatment to remove glass surface film
Inventor: OSTWALD ROBERT DR ING
IPC: C04B41/52
Filed: 1991-11-21
Abstract: Metallisation of Al nitride ceramic, exhibiting surface enrichment of sintering aid in the form of a glass film, is carried out by removing or perforating the film by mechanical pretreatment and intermediate treatment, finely roughening the ceramic surface by chemical post-treatment and then metallising the ceramic surface in two stages to provide an adherent metal layer. USE/ADVANTAGE - The metallised AlN ceramic is useful as a substrate for highly integrated logic circuits and for power electronics. An adherent and uniform metallisation is obtd. without use of adhesion promoters and with only slight roughening of the ceramic surface (thus allowing fine circuit line prodn.).
