发明名称 Double capacitor and manufacturing method thereof
摘要 A double capacitor and the method of manufacturing the same contains two capacitors connected in parallel within a semiconductor integrated circuit. A common ground conductor used by both capacitors is formed using a tri-layer mask and sputtering process that gives the conductor a U shape, which results in a larger charging capacity compared with a conventional capacitor using the same chip area.
