Multi-Wire Electrical Discharge Slicing for Silicon Carbide

In this paper, we propose a new wafer slicing method for silicon carbide(SiC). SiC is well-known as a difficult-to-cut material, and a conventional slicing via multi-wire saw becomes more difficult with increasing ingot size. To solve this problem, the multi-wire electrical discharge slicing (EDS) method is applied to 100 mm-square SiC polycrystalline block.

Silicon Ingot Production

A mono-crystalline silicon seed crystal is brought into contact with one end of a poly-crystalline silicon ingot in the fl oat-zone (FZ) or zone melting process as schematically shown in Fig. 5. Starting from here, an RF coil melts a small region of the polysilicon which, after cooling down, forms mono-crystalline silicon
