Kelvin Dao 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: 9330994
    Abstract: A semiconductor device has a semiconductor die and encapsulant deposited over the semiconductor die. An insulating layer is formed over the semiconductor die and encapsulant. A first channel including a first conductive surface is formed in the insulating layer by laser radiation. A laser-activated catalyst is infused in the insulating layer to form the first conductive surface in the first channel upon laser radiation. A vertical interconnect is formed through the encapsulant. A first conductive layer is formed in the first channel over the first conductive surface. A second channel including a second conductive surface is formed in the encapsulant by laser radiation. The catalyst is infused in the encapsulant to form the second conductive surface in the second channel upon laser radiation. A second conductive layer is formed in the second channel over the second conductive surface. An interconnect structure is formed over the first conductive layer.

  • Publication number: 20150179602
    Abstract: An integrated circuit packaging system and method of manufacture thereof including: an integrated circuit die having a contact pad; a redistribution layer on the contact pad, the redistribution layer having a chip contact, a trace, and a bump pad, the redistribution layer having a curved top surface and sidewalls which are planar; an upper passivation layer on the sidewalls of the redistribution layer with the area above the bump pad of the redistribution layer exposed from the upper passivation layer; and an external interconnect attached over the bump pad.
