  • Patent number: 11978664
    Abstract: A method includes forming a first conductive feature over a semiconductor substrate, forming an ILD layer over the first conductive feature, patterning the ILD layer to form a trench, and forming a conductive layer over the patterned ILD layer to fill the trench. The method further includes polishing the conductive layer to form a via contact configured to interconnect the first conductive feature with a second conductive feature, where polishing the conductive layer exposes a top surface of the ILD layer, polishing the exposed top surface of the ILD layer, such that a top portion of the via contact protrudes from the exposed top surface of the ILD layer, and forming the second conductive feature over the via contact, such that the top portion of the via contact extends into the second conductive feature.

  • Patent number: 9683098
    Abstract: The disclosure is related to colored contact lenses including a transparent protective layer, a colored layer and a lens layer, wherein the colored layer is between the transparent protective layer and the lens layer. A composition for forming the transparent protective layer includes at least one first hydrophilic monomer and a first thickener. A composition for forming the colored layer includes at least one second hydrophilic monomer, an adhesive resin, a second thickener and a colorant. At least one of the thickeners used for forming the transparent protective layer and the color layer is a modified polyvinylpyrrolidone.

  • Publication number: 20150338681
    Abstract: A method for manufacturing a colored contact lens which comprises the steps of: (a) forming a contact lens by polymerizing a polymerizable lens forming material in a mold, wherein the lens forming material includes at least one reactive group; (b) contacting at least a part of the contact lens with a dye solution for a period of time sufficient to form a colored layer within the contact lens, wherein the dye solution includes at least one dye of ?-sulphatoethyl sulphone substituted with a sulfonate group; (c) immersing the contact lens with colored layer in a fixing solution; and (d) washing the contact lens; wherein the colored layer is covalently attached to the contact lens.
