The wafers are sawed inside a circular blade whose cutting edge is fi lled with diamond splinters (Fig. 17). After sawing, the wafer surfaces are already relatively fl at and smooth, so the subsequent lapping of the surfaces takes less time and eff ort. However, only one wafer per annular saw can be cut at the same time, so this technique has a comparably low throughput which makes the ...
