METHOD OF SINGULATING SEMICONDUCTOR WAFER HAVING A PLURALITY OF DIE AND A BACK LAYER DISPOSED ALONG A MAJOR SURFACE

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.

Method of singulating semiconductor wafer having a plurality of die and a back layer disposed along a major surface

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.

Dividing device for wafer

A dividing device divides a wafer from an ingot by slicing the ingot by using a dividing layer which is formed by relatively moving a laser beam to a predetermined depth of the ingot from one of both end faces of the ingot. The dividing device for a wafer includes: first fixing part that fixes the other of the both end faces of the ingot; second fixing part that is arranged on a first central axis line of the ingot so as to face the first fixing part and fixes the one of the both end faces of the ingot; and tension part that apply a tensile force to the ingot via the first and second fixing parts. The tension part rotates one end of the dividing layer with another end as a fulcrum so as to generate moments for slicing the ingot with the dividing layer as a boundary.
