Abstract:
1. An electrostatic discharge device, comprising: a P-substrate; an N-well, formed in said P-substrate; a first N+ region, formed adjacent to said N-well, said first N+ region being isolated from said N-well; a first P+ region, formed adjacent to said N-well, said first P+ region being isolated from said N-well and said first N+ region; a plurality of second P+ regions formed inside said N-well; a plurality of second N+ regions formed inside said N-well, two of said second N+ regions being located adjacent to boundaries of said N-well; a first electrode, connecting to at least one of said second N+ regions and at least one of said second P+ region located adjacent to said second N+ region via a first electrical conductor, wherein said first electrical conductor is made of a metal; and a second electrode, connecting to at least one of said first P+ regions and at least one of said first N+ regions via a second electrical conductor, wherein said second electrical conductor is made of said metal.
