  • Patent number: 9443137
    Abstract: Provided is an apparatus and method for detecting body parts, the method including identifying a group of sub-images relevant to a body part in an image to be detected, assigning a reliability coefficient for the body part to the sub-images in the group of sub-images based on a basic vision feature of the sub-images and an extension feature of the sub-images to neighboring regions, and detecting a location of the body part by overlaying sub-images having reliability coefficients higher than a threshold value.
    Type: Grant
    Filed: April 5, 2013
    Date of Patent: September 13, 2016
    Assignee: Samsung Electronics Co., Ltd.

  • Patent number: 7276797
    Abstract: A structure and method for an improved a bond pad structure. A top wiring layer and a top dielectric (IMD) layer over a semiconductor structure are provided. The buffer dielectric layer is formed over the top wiring layer and the top dielectric (IMD) layer. A buffer opening is formed in the buffer dielectric layer exposing at least of portion of the top wiring layer. A barrier layer is formed over the buffer dielectric layer, and the top wiring layer in the buffer opening. A conductive buffer layer is formed over the barrier layer. The conductive buffer layer is planarized to form a buffer pad in the buffer opening. A passivation layer is formed over the buffer pad and the buffer dielectric layer. A bond pad opening is formed in the passivation layer over at least a portion of the buffer pad. A bond pad support layer is formed over the buffer pad and the buffer dielectric layer. A bond pad layer is formed over the bond pad support layer.
