Jacky Chang 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).

  • Patent number: 9006097
    Abstract: A method of forming a bump structure includes providing a semiconductor substrate and forming an under-bump-metallurgy (UBM) layer on the semiconductor substrate. The method further includes forming a mask layer on the UBM layer, wherein the mask layer has an opening exposing a portion of the UBM layer. The method further includes forming a copper layer in the opening of the mask layer and removing a portion of the mask layer to form a space between the copper layer and the mask layer. The method further includes performing an electrolytic process to fill the space with a metal layer and removing the mask layer.
    Type: Grant
    Filed: June 26, 2013
    Date of Patent: April 14, 2015
    Assignee: Taiwan Semiconductor Manufacturing Company, Ltd.

  • Publication number: 20130248232
    Abstract: A conductive pattern film substrate and manufacturing method for combining two anisotropic materials, namely a patterned body and a film layer, without assistance from an intermediate layer. The method includes producing a thermal spraying source for performing a heating operation on a film material to prepare the film material for thermal spraying or semi-thermal spraying and thereby decompose the film material into film particles; and spraying the film particles to a pattern layer disposed on the body and having the pattern by the thermal spraying source to form the film layer having the film particle on the pattern layer, thereby enabling the body to embody electrical characteristics of the pattern.
