摘要： A damascene structure and method of making the same in a low k dielectric material employs an imageable layer in which the damascene pattern is provided. The imageable layer is a convertible layer that upon exposure to the plasma etch that etches the low k dielectric material, converts the silicon-rich imageble layer into a mask layer containing silicon dioxide, for example. The low k dielectric material is protected from further etching by the mask thus created.

A plurality of stacked gate layers are formed on a semiconductor substrate, wherein each stacked gate layer extends in a predefined direction and is substantially parallel to other stacked gate layers. An interlayer insulating layer is deposited over the plurality of stacked gate layers, and a contact hole is patterned between a first stacked gate layer of the plurality of stacked gate layers and a second stacked gate layer of the plurality of stacked gate layers. The contact hole is formed in an elongated shape, wherein a major axis of the contact hole is substantially parallel to the stacked gate layers. A conductive layer is deposited in the contact hole and excess conductive material is removed.
