Abstract
Etch masks and methods of dicing semiconductor wafers are described. In an example, an etch mask for a wafer singulation process includes a water-soluble matrix based on a solid component and water. The etch mask also includes a plurality of particles dispersed throughout the water-soluble matrix. The plurality of particles has an average diameter approximately in the range of 5-100 nanometers. A ratio of weight % of the solid component to weight % of the plurality of particles is approximately in the range of 1:0.1-1:4.
