Abstract
A semiconductor device has structures to reduced stress notching effects in conductive lines. In one form, the semiconductor device includes a semiconductor die which has a plurality of active conductive lines thereon. The plurality of conductive lines collectively has a first and a second outside edge. In close proximity to each of the first and the second outside edges is a stress reducing line. Each of the stress reducing lines is a non-active structure (in other words does not transmit signals) and functions to reduce stress concentrations on the plurality of active conductive lines which are imposed by overlying insulating and passivation layers. As a result of weakened stress concentrations, the amount of stress notching in the active conductive lines is reduced.
