A method used during the manufacture of a semiconductor device comprises providing a semiconductor wafer assembly, the assembly including a plurality of unsegmented semiconductor dice. A coating layer is formed over the semiconductor wafer assembly which causes the wafer to warp, for example through a surface tension exerted on the wafer assembly by the coating layer. To reduce wafer warp a series of grooves is etched or cut into the coating layer. The grooves are believed to relieve surface tension exerted on the wafer by the coating layer. An inventive structure resulting from the method is also described.
