摘要:
A method of forming air gaps within a solid structure is provided. In this method, a sacrificial material is covered by an overlayer. The sacrificial material is then removed through the overlayer to leave an air gap. Such air gaps are particularly useful as insulation between metal lines in an electronic device such as an electrical interconnect structure. Structures containing air gaps are also provided.

摘要:
A process for efficient modification and metallization of substrates includes the steps of providing a substrate with highly photoefficient chemical functional groups on at least a portion of this substrate, exposing the substrate to actinic radiation to transform, deactivate, or remove these chemical functional groups, to modify their chemical reactivity, and carrying out further chemical reaction steps on these modified chemical functional groups.
摘要:
The invention is directed to a process for patterning a substrate in a selective pattern. In one embodiment, the process comprises the steps of forming a patterned coating over a substrate surface whereby portions of the substrate are covered by the patterned coating and portions of the substrate remain uncoated. A layer of a ligating material is coated over at least those portions of the substrate free of the patterned coating. The ligating layer is one that is capable of ligating with an electroless metal plating catalyst. The article so formed is then contacted with an electroless metallization catalyst and then with an electroless plating solution to form a patterned metal deposit on the substrate.
摘要:
Methods and compositions for electroless metallization. In one aspect, the invention is characterized by the use of chemical groups capable of ligating with an electroless metallization catalyst, including use of ligating groups that are chemically bound to the substrate. In a preferred aspect, the invention provides a means for selective metallization without the use of a conventional photoresist patterning sequence, enabling fabrication of high resolution metal patterns in a direct and convenient manner.
