This is because the etch-stopping dielectric layer was removed at the wafer edge during the edge trim process. If edge trim stops before reaching the bonding interface, and a Si RIE process is applied to remove post-grinding remaining silicon, then dangling membranes can form at the wafer edge bevel area, eventually becoming flake defects."Web

Equally crucial to further the semiconductor roadmap are grinding and dicing (cutting) technologies. Like wafer testing, grinding and dicing systems are dominated by only 2 players – DISCO Corporation and Tokyo Seimitsu. In the 1960s, semiconductor silicon wafer was only 23mm in diameter, and 275 microns in thickness.Web

Grinding wheels : In general, grinding typically involves Z1 & Z2 grinding wheels where Z1 is coarse grinding ( < #500 grit grinding wheel) and removes most of the Silicon (~ 500 – 600um). Z2 grinding is a fine grinding process ( typically < #3000 grit grinding wheel, but can be little finer) and removes about 20-50um of Silicon.Web

Edge trimming will allow the resultant device wafer to be ground extremely thin, with some applications requiring a thickness of 50 µm (for TSV) or even much thinner (for BSI). The edge of the silicon wafer is shaped in an edge grinding step (various shapes are used) to minimize edge chipping and flaking. Later, during the CMP process the …Web

Wheels. By changing from a vitrified bond (VS, VS202, etc), which has been used for rough grinding on Z1-axis, to a resin bond BT100 (Photo 4), it is possible to lower damage and suppress edge chipping *1, which is a cause of wafer breakage.Furthermore, by employing aZ2-axis wheel with BK-09 bond, which supports a larger removal of Z1-axis grinding …Web

Abstract. In today's polishing industry there is a great demand for obtaining a smooth, extremely flat, and mirror-like and particle free surface of silicon wafer for implanting semiconductor devices over it. In this direction, Chemical Mechanical Polishing (CMP) and its allied processes have played a vital role in the present and past scenario.Web

Only single-side grinders that grind one side of the wafer can be used for back grinding. Initially used ones are of Blanchard type and creep-feed type (rotary-table vertical-spindle) [37], [38], [39]. Fig. 3 illustrates the Blanchard-type wafer grinder. A rotary table has several chucks aligned along a circle, and each chuck holds a silicon wafer.Web
