Abstract:
A method to determine and monitor concentrations of inert metal plating components in metal plating baths. An inert indictor is included in the bath composition and the concentration of the inert indictor is monitored during plating. The change in the concentration of the inert indicator is used to determine the change in the concentration of inert bath components.
Abstract:
This invention provides a process for electroless copper plating without using formaldehyde and an electroless copper plating solution which is used in the process. To this end, there is disclosed a process for electroless copper plating, which treatment comprises depositing a palladium or palladium-tin catalyst on a resin substrate, and then treating said resin substrate having the catalyst deposited thereon with a formaldehyde-free electroless copper plating solution that contains copper ions and a reducing agent, wherein the need for an accelerating treatment of a catalyst after said catalyst depositing treatment is obviated. The productivity of a copper-resin composite material is dramatically enhanced by the process of the present invention, because a copper thin layer can be formed on the resin substrate in a short time, even if an accelerating treatment for a catalyst is not performed in a separate process.
Abstract:
Electrically resistive material including platinum and from about 5 and about 70 molar percent of iridium, ruthenium or mixtures thereof, calculated based on platinum as 100%, are disclosed.
Abstract:
A method of manufacturing electronic devices containing one or more layers of materials that are sensitive to the strong chemicals used to remove cross-linked polymeric layers such as photoresists and antireflective coatings is provided. The cross-linked polymeric layers can be easily removed following etching through the use of certain removable layers disposed between the substrate and the cross-linked polymeric layers.
Abstract:
Provided are methods of forming optical waveguides. The methods involve: (a) forming over a substrate a layer of a photodefinable composition; (b) exposing a portion of the layer to actinic radiation; (c) developing the exposed layer to form a waveguide core structure; and (d) heating the waveguide core structure to a temperature and for a time effective to reflow the structure such that it becomes at least partially rounded in cross-section. Also provided are optical waveguides formed from the described methods and electronic devices including one or more of the optical waveguides.
Abstract:
A method for electrolytic copper plating using an electrolytic copper plating solution including a compound containing a structure of nullXnullSnullYnull, wherein X and Y are independently chosen from hydrogen atom, carbon atom, sulfur atom, nitrogen atom, and oxygen atom, and X and Y may be the same only when they are a carbon atom, and by contacting the electrolytic copper plating solution with ozone is disclosed.
Abstract:
In a first aspect, organic coating compositions are provided, particularly spin-on antireflective coating compositions, that contain a polyester resin component. In a further aspect, coating compositions are provided that contain a resin component obtained by polymerization of a multi-hydroxy compound. Coating compositions of the invention are particularly useful employed in combination with an overcoated photoresist layer to manufacture integrated circuits.
Abstract:
New photoresists are provides that are suitable for short wavelength imaging, particularly sub-170 nm such as 157 nm. Resists of the invention comprise a fluorine-containing polymer, a photoactive component, and a solvent component. Preferred solvents for use on the resists of the invention can maintain the resist components in solution and include one or more preferably two or more (i.e. blends) of solvents. In particularly preferred solvent blends of the invention, each blend member evaporates at substantially equal rates, whereby the resist composition maintains a substantially constant concentration of each blend member.
Abstract:
The present invention provides radiation sensitive compositions and methods that comprise novel means for providing relief images of enhanced resolution. In one aspect the invention provides a method for controlling diffusion of photogenerated acid comprising adding a polar compound to a radiation sensitive composition and applying a layer of the composition to a substrate; exposing the composition layer to activating radiation whereby a latent image is generated comprising a distribution of acid moieties complexed with the polar compound; and treating the exposed composition layer to provide an activating amount of acid.
