发明名称 Method for fabricating semiconductor device
摘要 A method for fabricating a semiconductor device capable of preventing an electric short between lower electrodes caused by leaning lower electrodes, or lifted lower electrodes and of securing a sufficient capacitance of a capacitor by increasing an effective capacitor area. The method includes the steps of: preparing a semi-finished semiconductor substrate; forming a sacrificial layer on the semi-finished semiconductor substrate; patterning the sacrificial layer by using an island-type photoresist pattern, thereby obtaining at least one contact hole to expose portions of the semi-finished semiconductor substrate; and forming a conductive layer on the sacrificial layer.
