摘要:
A process of producing a substrate is described. The process involves mixing intensively a starting mixture comprising silicon power, Si3N4, an silicon-organic polymer, and optionally an anhydrous organic pressing oil, thereby forming an intermediate mixture. The intermediate mixture is then shaped by a method selected from dry pressing, slip casting, hot pressing, extrusion casting, or tape casting, thereby forming an intermediate shaped article. The intermediate shaped article is then crosslinked and pyrolyzed in an inert atmosphere, thereby forming a crosslinked and pyrolyzed shaped article. The crosslinked and pyrolyzed shaped article is next nitrided, resulting in the formation of a nitrided shaped article, which may be optionally sintered, thereby forming the substrate. The substrates of the present invention may be used in the fabrication of semiconductor components, such as thin film solar cells.
