    摘要: A method of etching a ferroelectric device 100 having a ferroelectric layer 112 between a top and a bottom electrode 114, 108 is disclosed herein. Hardmasks 116, 118 are deposited on the top electrode 114, two or more hardmasks being spaced apart by narrow first regions 115 and spaced apart from other hardmasks by wider second regions 117. The top electrode 114 and ferroelectric layer 112 are then etched to pattern the top electrode 114 thus forming capacitors 102, 104, and the bottom electrode 108 is etched by a process in which the second regions are etched more slowly than the second regions. Those capacitors having a first region between them have a common bottom electrode 108, but in the second regions the bottom electrode is severed. To pattern the bottom electrode 108, a fluorine-based chemistry followed thereafter by a CO-based chemistry are used in a two step etching process.

    摘要: A ferroelectric capacitor device, such as an FeRAM device is formed by forming a substrate extending in a first plane and comprising a number of layers of material, forming a hard mask layer on the substrate and forming a first layer of a first material on the hard mask layer. The hard mask shape is then defined by etching the hard mask layer. A second layer of the first material is deposited on the etched hard mask layer. The deposited second layer has one or more side surfaces extending substantially perpendicular to the plane of the substrate. The second layer and the number of layers forming the substrate are then etched to shape the ferroelectric capacitor device.

    摘要: A ferroelectric capacitor is fabricated using a noble metal hardmask. A hardmask is deposited on a top electrode of a capacitor stack comprising a ferroelectric layer sandwiched between the top electrode and a bottom electrode. The top electrode is patterned according to the pattern of the hardmask by etching at a first temperature. The top electrode serves as the noble metal hardmask and the ferroelectric layer is patterned according to the pattern of the top electrode at a second temperature lower than the first temperature, resulting in the top electrode having sidewalls beveled relative to a top surface of the top electrode etching. The bottom electrode is etched at a third temperature to form the capacitor.
