    • Methods are provided for fabricating semiconductor devices having capacitors, which prevent lower electrodes of the capacitors from breaking or collapsing and which provide increased capacitance of the capacitors. For instance, a method includes forming a first insulating layer on a semiconductor substrate, forming a first hole in the first insulating layer, forming a contact plug in the first hole, forming a second insulating layer having a landing pad, wherein the landing pad contacts an upper surface of the contact plug, forming an etch stop layer on the landing pad and the second insulating layer, forming a third insulating layer on the etch stop layer, forming a third hole through the third insulating layer and etch stop layer to expose the landing pad, selectively etching the exposed landing pad, forming a lower electrode on the selectively etched landing pad, and then forming a capacitor by forming a dielectric layer and an upper electrode on the lower electrode.

    • Methods of fabricating a flash memory device and flash memory devices fabricated thereby are provided. One of the methods includes forming an isolation layer in a semiconductor substrate to define a plurality of parallel active regions in the semiconductor substrate. A plurality of first conductive layer patterns are formed on the active regions. The first conductive layer patterns are spaced apart from each other in a lengthwise direction of the active regions. An insulating layer is conformally formed on the semiconductor substrate and the first conductive layer patterns. A second conductive layer is formed on the insulating layer. The second conductive layer is patterned until the insulating layer is exposed to form a plurality of parallel second conductive layer patterns. The second conductive layer patterns cross the active regions and the isolation layer to overlap the first conductive layer patterns.
    • 提供了制造闪速存储器件的方法和由此制造的闪存器件。 一种方法包括在半导体衬底中形成隔离层以在半导体衬底中限定多个平行的有源区。 在有源区上形成多个第一导电层图案。 第一导电层图案在活性区域的长度方向上彼此间隔开。 在半导体衬底和第一导电层图案上共形形成绝缘层。 在绝缘层上形成第二导电层。 图案化第二导电层直到绝缘层暴露以形成多个平行的第二导电层图案。 第二导电层图案与有源区和隔离层交叉,以与第一导电层图案重叠。
