Latest Patents

Miyashita holds a patent for a thin-film circuit substrate. The objective of her invention is to provide a reliable substrate that features minute via plugs at a fine pitch. This is achieved by forming an insulation layer that acts as an etching stopper on a silicon substrate. Via holes are then created in the silicon substrate using a semiconductor process until the etching stopper layer is exposed. A thin-film circuit is subsequently formed on the insulation layer, which is removed at the via holes to expose the thin-film circuit. The thin-film circuit may undergo heat treatment, and the via holes are filled with an electrically conductive material to form vamp electrodes. This innovative approach enhances the reliability and performance of electronic devices.
