The progress on laser metallization of aluminium nitride (AlN) ceramics and the problems in the process of metallization are introduced. The major solutions to these problems are proposed as well. Based on the laser thermal effect, the thermal decomposition occurs on the AlN surface by laser metallization, and the metal conductive layer is generated directly, which has the advantages of low cost, high efficiency, simple equipment maintenance and so on. The optimization methods of laser, beam quality and process parameters and the applications of AlN ceramic metallization are introduced. The development of AlN ceramic metallization in the future is prospected.
