Patent number: 6531226Abstract: A multilayer brazeable metallization structure for diamond components is described. The brazeable metallization finds particular application for the attachment of diamond components such as heat spreaders in electronic packages that incorporate high power semiconductor devices. In the present invention, a diamond component is provided with a multilayer coating of metals including a first layer of chromium for adhesion, a second barrier layer of a refractory metal for a barrier that may be alloyed with chromium, and a top layer of copper, silver or gold for wetting. The refractory metals for the second layer include tungsten, molybdenum, tantalum and niobium. Tungsten or tungsten-chromium alloy is preferred as the second layer. This multilayer metallization structure provides a robust interface between diamond and standard brazing alloys which are used to join the diamond to electrical leads or a flange made of metals such as copper-tungsten.Type: GrantFiled: May 30, 2000Date of Patent: March 11, 2003Assignee: Morgan Chemical Products, Inc.Inventor: Ronald R. Petkie

Patent number: 6528180Abstract: A method for metallizing integrated circuits is disclosed. In one aspect, an integrated circuit is metallized by depositing liner material on a substrate followed by one or more metal layers. The liner material is selected from the group of tantalum (Ta), tantalum nitride (TaN), niobium (Nb), niobium nitride (NbN), vanadium (V), vanadium nitride (VN), and combinations thereof. The liner material is preferably conformably deposited on the substrate using physical vapor deposition (PVD). The one or more metal layers are deposited on the barrier layer using chemical vapor deposition (CVD), physical vapor deposition (PVD), or a combination of both CVD and PVD.Type: GrantFiled: May 23, 2000Date of Patent: March 4, 2003Assignee: Applied Materials, Inc.Inventors: Wei Ti Lee, Ted Guo, Gongda Yao
