Abstract
PURPOSE:To facilitate formation of a wiring layer which has excellent heat resistant properties and layer strength against soldering heat treatment conditions by providing a wiring layer composed of a bonding layer made of titanium, a barrier layer made of copper and one of tungsten and molybdenum and a main conductor layer which are formed successively on a ceramic substrate made of sintered silicon carbide. CONSTITUTION:A bonding layer 2 and a barrier layer 3 are formed on a ceramic substrate 1 made of silicon carbide ceramic by a vapor growth method and further a main conductor layer 4 is formed. The main conductor layer 4 is provided for forming an electric wiring constituting a predetermined electric circuit on the substrate 1, the bonding layer 2 is provided for improving the adhesiveness with the substrate 1 and the barrier layer 3 is provided for avoiding mutual diffusion between the bonding layer 2 and the main conductor layer 4. The bonding layer 2 is made of titanium and the barrier layer made of copper and one of tungsten and molybdenum is formed on the bonding layer 2 and then the main conductor layer 4 is formed on the barrier layer 3.
