Patents by Inventor Heraldo Botelho

Heraldo Botelho has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Publication number: 20060222771
    Abstract: A method is provided for forming an amorphous carbon layer, deposited on a dielectric material such as oxide, nitride, silicon carbide, carbon doped oxide, etc., or a metal layer such as tungsten, aluminum or poly-silicon. The method includes the use of chamber seasoning, variable thickness of seasoning film, wider spacing, variable process gas flows, post-deposition purge with inert gas, and post-deposition plasma purge, among others, to make the deposition of an amorphous carbon film at low deposition temperatures possible without any defects or particle contamination.
    Type: Application

  • Publication number: 20050199585
    Abstract: Methods are provided for processing a substrate including etching conductive materials with amorphous carbon materials disposed thereon. In one aspect, the invention provides a method for processing a substrate including forming a conductive material layer on a surface of the substrate, depositing an amorphous carbon layer on the conductive material layer, etching the amorphous carbon layer to form a patterned amorphous carbon layer, and etching feature definitions in the conductive material layer corresponding to the patterned amorphous carbon layer. The amorphous carbon layer may act as a hardmask, an etch stop, or an anti-reflective coating.
