Patent number: 5804288Abstract: A formed aluminum nitride piece is produced by applying a wiring layer-forming metal paste containing such a high melting temperature metal (wiring metal) as tungsten, for example, to an aluminum nitride green sheet and shaping one layer of the aluminum nitride green sheet now bearing the applied metal paste or superposing a plurality of such layers. In this case, a manganese component destined to densify tungsten is incorporated in at least either of the green sheet and the wiring layer-forming metal paste. The manganese component is either manganese as a simple metallic element or such a manganese compound as manganese oxide. Then, the formed aluminum nitride piece is fired to effect simultaneous sintering of an aluminum nitride and tungsten. Owing to the preparatory addition of the manganese component, a complex compound such as a complex oxide containing manganese and tungsten or a complex such as a eutectic alloy of manganese and tungsten is formed in the wiring metal layer.Type: GrantFiled: December 28, 1994Date of Patent: September 8, 1998Assignee: Kabushiki Kaisha ToshibaInventor: Jun Monma
