摘要:
Methods of controlling critical dimensions of reduced-sized features during semiconductor fabrication through pitch multiplication are disclosed. Pitch multiplication is accomplished by patterning mask structures via conventional photoresist techniques and subsequently transferring the pattern to a sacrificial material. Spacer regions are then formed on the vertical surfaces of the transferred pattern following the deposition of a conformal material via atomic layer deposition. The spacer regions, and therefore the reduced features, are then transferred to a semiconductor substrate.

摘要:
A method for patterning a layer increases the density of features formed over an initial patterning layer using a series of self-aligned spacers. A layer to be etched is provided, then an initial sacrificial patterning layer, for example formed using optical lithography, is formed over the layer to be etched. Depending on the embodiment, the patterning layer may be trimmed, then a series of spacer layers formed and etched. The number of spacer layers and their target dimensions depends on the desired increase in feature density. An in-process semiconductor device and electronic system is also described.

摘要:
A method for providing an isolation material, for example trench isolation for a semiconductor device, comprises forming a first dielectric such as silicon dioxide using an atomic layer deposition (ALD) process within a trench, partially etching the first dielectric, then forming a second dielectric such as a silicon dioxide using a high density plasma (HDP) deposition within the trench. The second dielectric provides desirable properties such as resistance to specific etches than the first dielectric, while the first dielectric fills high aspect ratio openings more easily than the second dielectric. Depositing the first dielectric results in a decreased trench aspect ratio which must be filled by the second dielectric.
