Patent ID: 8610277

Claim:
A bridge type pad structure of a semiconductor device, comprising: a first metal pad formed on a lower structure; an insulation layer formed on the lower structure and covering the first metal pad; metal contacts formed in the insulation layer and connected to the same first metal pad, end portions of the metal contacts contacting the same first metal pad, wherein each of the metal contacts comprises one of a cylindrical pillar shape or an elliptical pillar shape; a bridge formed in the insulation layer, the bridge connecting the metal contacts to one another; and a second metal pad provided on the insulation layer, the second metal pad being directly in contact with the metal contacts, wherein the bridge is connected to side faces of the metal contacts, and wherein a region of the bridge that is connected to the side faces of the metal contacts comprises a curved profile, and wherein a thickness of the bridge is smaller than a thickness of each of the metal contacts, and a height of an upper surface of the bridge above the first metal pad is substantially equal to a height of an upper surface of each of the metal contacts above the first metal pad.
