Black Carborundum

Black Carborundum Description

In the next few years, the proportion of large-size silicon carbide epitaxial wafers will increase year by year. As 4-inch silicon carbide substrate and epitaxial technology has become increasingly mature, therefore, 4-inch silicon carbide epitaxial wafer there is no longer a shortage of supply, its future price reduction space is limited. In addition, although the current international advanced manufacturers have developed 8-inch silicon carbide substrate, but its entry into the silicon carbide power device manufacturing market will be a long process, with the gradual maturation of the 8-inch silicon carbide epitaxial technology, the future may appear 8-inch silicon carbide power device production line.

Silicon carbide epitaxy mainly solves two major problems: epitaxial wafer uniformity control and epitaxial defect control.

(1) Epitaxial wafer uniformity control, due to the increase in epitaxial wafer size is often accompanied by a decline in epitaxial wafer uniformity, so the control of uniformity of large-size epitaxial wafer is the key to improve the yield and reliability of the device, and then reduce costs.

(2) Epitaxial defect control. Base crystal plane dislocation (BPD) is an important crystalline defect that affects the stability of silicon carbide bipolar power devices, and the continuous reduction of BPD density is the main direction for the development of epitaxial growth technology. Due to the high BPD density of silicon carbide substrates prepared by physical weather transport (PVT), most of the BPDs in the epitaxial layer that are harmful to the device come from the penetration of BPDs in the substrate into the epitaxial layer. Therefore, improving the substrate crystallisation quality can effectively reduce the BPD dislocation density in the epitaxial layer.
