A method for forming an electronic device includes providing a wafer having a plurality of die formed as part of the wafer and separated from each other by spaces. A layer of material is disposed atop a major surface of the wafer and the layer of material is placed adjacent to first carrier substrate comprising a first adhesive layer. The wafer is singulated through the spaces to form singulation lines. A second carrier substrate comprising a second adhesive layer is placed onto an opposite major surface of the wafer. The method includes moving a mechanical device adjacent to and in a direction generally parallel to one of the first carrier substrate or the second carrier substrate to separate the layer of material in the singulation lines. In one example, the second adhesive layer has an adhesive strength that is less than that of the first adhesive layer.

In a device for breaking out a workpiece (3) from a material sheet (2) through an opening (4) of a die (1) by means of a breakout tool (5), the die (1) is to have a plug-in unit (22), wherein a breakout module (9.1-9.4) is insertable into the plug-in unit (22), wherein the breakout module (9.1-9.4) is composed of an insert (10) and of a module lobe (11), wherein the insert (10) has a surface (16) and a shearing edge (17), wherein the shearing edge (17) toward a bearing face (12) of the module lobe (11) configures an offcut length (18), and wherein the offcut length has a height (h) of 0.8 mm to 1.8 mm, and preferably of 1.5 mm.

Die are singulated from a wafer having a back layer by placing the wafer onto a first carrier substrate with the back layer adjacent the carrier substrate, forming singulation lines through the wafer to expose the back layer within the singulation lines, and using a plate structure to apply a pressure to the wafer to separate the back layer in the singulation lines. The pressure can be applied through the first carrier substrate proximate to the back layer, or can be applied through a second carrier substrate attached to a front side of the wafer opposite to the back layer.
