Patent number: 6768205Abstract: The objective of the present invention is to provide a reliable thin-film circuit substrate or via formed substrate that is provided with minute via plugs at a fine pitch. The objective is served by forming an insulation layer that functions as an etching stopper on a Si substrate, and then via holes are formed in the Si substrate, using a semiconductor process, until the etching stopper layer is exposed. Further, a thin-film circuit is formed on the insulation layer, and the insulation layer is removed at the via holes such that the thin-film circuit is exposed. As necessary, the thin film circuit is heat-treated, and then the via holes are filled with an electrically conductive material and vamp electrodes are formed.Type: GrantFiled: March 1, 2002Date of Patent: July 27, 2004Assignee: Fujitsu LimitedInventors: Osamu Taniguchi, Tomoko Miyashita, Yasuo Yamagishi, Koji Omote, Yoshihiko Imanaka
