Fabriion of Pores in a Silicon Carbide Wafer by …
An electrochemical method for making pores in a silicon carbide (SiC) wafer, in which a glassy-carbon (GC) needle electrode was used for processing, is described. By bringing the GC electrode into contact with SiC at its tip end in 20 mol dm –3 HF solution and applying an anodic potential of or higher than 4 V vs Ag/AgCl to it, SiC was etched at the SiC/GC contact area, leading to pore

Process Technology for Silicon Carbide Devices
Silicon face Carbon face Silicon carbide is made up of equal parts silicon and carbon. Both are period IV elements, so they will prefer a covalent bonding such as in the left figure. Also, each carbon atom is surrounded by four silicon atoms, and vice versa.

Silicon Carbide SiC Material Properties
Silicon carbide ceramics with little or no grain boundary impurities maintain their strength to very high temperatures, approaching 1600 C with no strength loss. Chemical purity, resistance to chemical attack at temperature, and strength retention at high temperatures has made this material very popular as wafer tray supports and paddles in semiconductor furnaces.
Basic Parameters of Silicon Carbide (SiC)
Silicon carbide crystallizes in numerous (more than 200 ) different modifiions (polylypes). The most important are: cubic unit cell: 3C-SiC (cubic unit cell, zincblende); 2H-SiC; 4H-SiC; 6H-SiC (hexagonal unit cell, wurtzile ); 15R-SiC (rhoohedral unit cell).-SiC (rhoohedral unit cell).
