Abstract:
1. An electrical fuse device comprising: an anode disposed on a substrate, the anode having a width in a first direction and a length in a second direction parallel to the first direction; a cathode disposed on the substrate separate from the anode, the cathode having a width parallel to the first direction and a length parallel to the second direction; a fuse link extending lengthwise parallel to the second direction between the anode and the cathode, the fuse link coupled to the anode and the cathode, and the fuse link having a width parallel to the first direction; a first cathode contact coupled to the cathode, the first cathode contact having a width parallel to the first direction that is greater than the width of the fuse link; and a first anode contact coupled to the anode, the first anode contact having a width parallel to the first direction that is greater than the width of the fuse link, an anode transition region interposed between the anode and the fuse link, the anode transition region having a width parallel to the first direction, wherein the first cathode contact is disposed to cross a virtual extending surface of the fuse link in a cathode direction and the first anode contact is disposed to cross a virtual extending surface of the fuse link in an anode direction, wherein the width of the anode, the width of the fuse link, the width of the anode transition region are substantially same.
