Methods for protecting edges of semiconductor dies are disclosed. Further, the disclosed methods provide for separating the semiconductor dies without using a dicing technique. In one embodiment, a plurality of trenches may be formed on a front side of a substrate including a plurality of semiconductor dies. Individual trenches may correspond to scribe lines of the substrate where each trench includes a depth greater than a final thickness of the semiconductor dies. A dielectric layer may be formed on sidewalls of the trenches, thereby protecting the edges of the semiconductor dies, prior to filling the trenches with an adhesive material. Subsequently, the substrate may be thinned from a back side such that the adhesive material in the trenches may be exposed from the back side. The adhesive material may be removed to singulate individual semiconductor dies of the plurality from the substrate.
