    摘要: Lithography masks and methods of manufacture thereof are disclosed. For example, a method of manufacturing a lithography mask includes forming a stack over a substrate. The stack includes bottom attenuated phase shift material layers, intermediate opaque material layers, and finally top resist layers. The method further includes patterning the stack and then trimming the resist layers to uncover a portion of the opaque material layers. The uncovered opaque material layers are subsequently etched followed by removal of any remaining resist layers.

    摘要: Methods for manufacturing semiconductor devices are disclosed. One preferred embodiment is a method of processing a semiconductor device. The method includes providing a workpiece having a material layer to be patterned disposed thereon. A masking material is formed over the material layer of the workpiece. The masking material includes a lower portion and an upper portion disposed over the lower portion. The upper portion of the masking material is patterned with a first pattern. A polymer material is disposed over the masking material. The masking material and the polymer layer are used to pattern the material layer of the workpiece.

    摘要: The prevention of active area loss in the STI model is disclosed which results in an improved device performance in devices manufactured according to the process flow. The process generally shared among the multiple various embodiments inverts the current conventional STI structure towards a process flow where an insulator is patterned with tapered trenches. A segregation layer is formed beneath the surface of the insulator in the tapered trenches. The tapered trenches are then filled with a semiconductor material which is further processed to create a number of active devices. Therefore, the active devices are created in patterned dielectric instead of the STI being created in the semiconductor substrate of the active devices.

    摘要: A process of using a-C:H layer as a hardmask material with tunable etch resistivity in a RIE process that alleviates the addition of a layer forming gas to the etchant when making a semiconductor device, comprising: a) providing a semiconductor substrate; b) forming a hardmask of amorphous carbon-hydrogen (a-C:H) layer by plasma enhancement over the semiconductor substrate; c) forming an opening in the hardmask layer to form an exposed surface portion of the hardmask layer; and d) etching the exposed surface portion of the hardmask layer without the addition of a layer forming gas using RIE to form a trench feature with sufficient masking and side wall protection.
