What it is

The Meyer Burger DW 288 is a multi-wire saw, also referred to as a wire cutter, designed for slicing hard and brittle materials. The DW 288 S4 variant is a smart slicing technology optimized for the semiconductor and sapphire industry, with capability for 8-inch workpieces.^[3]^[4]^[2]^[1]

How it works

General reference — not yet source-verified

In operation, the wire runs continuously over grooved guide rollers, forming a parallel web. The workpiece is mounted on a feed table and advanced into the wire web, which cuts through the material. The rocking motion of the workpiece helps to reduce kerf loss and improve surface quality.

Where it fits in the process flow

General reference — not yet source-verified

Wire sawing is a slicing step in the wafer manufacturing process, performed after crystal growth and ingot preparation. The output of the wire saw is a set of thin wafers that then undergo edge grinding, lapping, polishing, and cleaning.

Applications

General reference — not yet source-verified

Applications include the production of wafers for integrated circuits, LEDs, and power electronics. The wire saw can also be used for cutting other brittle materials such as glass and ceramics.
