On the use of diamond in a multichip power module (MCPM) based induction motor drive

The unique combination of excellent thermal, electrical, and mechanical properties makes synthetic diamond a legitimate material candidate for thermal management strategies in integrated drive modules. Over the past several years, joint research programs between academe have resulted in substantial diamond synthesis and post-synthesis processing time and cost, This is largely attributed to major advances in diamond synthesis using chemical vapor deposition (CVD) techniques. In this paper, an overview of diamond synthesis and post-synthesis processing is presented followed by a comparison of thermal heat spreading efficacy of silicon and CVD-diamond substrates for power electronic applications.
