Abstract
One aspect of the invention provides an integrated circuit (IC). The IC comprises transistors and contact fuses. The contact fuses each comprise a conducting layer, a frustum-shaped contact has a narrower end that contacts the conducting layer and a first metal layer that is located over the conducting layer. A wider end of the frustum-shaped contact contacts the first metal layer. The frustum-shaped contact has a ratio of an opening of the wider end to the narrower end that is at least about 1.2. The contact fuses each further include a heat sink that is located over and contacts the first metal layer.
