Abstract:
A method of separating a wafer into individual dies, the method comprising the steps of:forming a substrate of a ceramic material;forming organic multiple layers over the surface of said ceramic substrate;removing a portion of said organic multiple layers along a scribe line to form a groove to expose a portion of the surface of said ceramic substrate, said removing step forming two spaced parallel side walls defined by peripheral edges of the organic multiple layers, said side walls being connected to and extending from said ceramic substrate and cooperating with said exposed portion of the surface of said ceramic substrate to define said groove, said exposed portion being flat and extending across the scribe line;inserting a saw blade that has a thickness less than a width of said groove into said groove out of interference contact with said two spaced parallel side walls; andsawing said substrate inwardly from said exposed portion thereof along the scribe line with said saw blade.
