Method and structure for minimizing the downsides associated with microelectronic device processing adjacent porous dielectric materials are disclosed. In particular, chemical protocols are disclosed wherein porous dielectric materials may be sealed by attaching coupling agents to the surfaces of pores. The coupling agents may form all or part of caps on reactive groups in the dielectric surface or may crosslink to seal pores in the dielectric.

A semiconductor structure may be covered with a thermally decomposing film. That film may then be covered by a sealing cover. Subsequently, the thermally decomposing material may be decomposed, forming a cavity.
摘要:
A cap may be formed anisotropically over a photoresist feature. For example, a material, such as a polymer, may be coated over the photoresist feature. If the coated material is photoactive, the cap may be grown preferentially in the vertical direction, creating high aspect ratio structures in some embodiments of the present invention.
摘要:
Multiple-layer films in integrated circuit processing may be formed by the phase segregation of a single composition formed above a semiconductor substrate. The composition is then induced to phase segregate into at least a first continuous phase and a second continuous phase. The composition may be formed of two or more components that phase segregate into different continuous layers. The composition may also be a single component that breaks down upon activation into two or more components that phase segregate into different continuous layers. Phase segregation may be used to form, for example, a sacrificial light absorbing material (SLAM) and a developer resistant skin, a dielectric layer and a hard mask, a photoresist and an anti-reflective coating (ARC), a stress buffer coating and a protective layer on a substrate package, and light interference layers.

摘要:
Several techniques are described for modulating the etch rate of a sacrificial light absorbing material (SLAM) by altering its composition so that it matches the etch rate of a surrounding dielectric. This is particularly useful in a dual damascene process where the SLAM fills a via opening and is etched along with a surrounding dielectric material to form trenches overlying the via opening.

摘要:
A composite sacrificial material is deposited in a void or opening in a dielectric layer on a semiconductor substrate. The composite sacrificial material includes a polymeric or oligomeric matrix with filler material mixed therein. The filler material may be particulate matter that may be used to modify one or more properties of the composite sacrificial material during semiconductor processing.
