WebSiC substrates are higher cost than Si but have been successfully used for LED manufacturing processes. Much of the LEDs produced by Cree (who also manufacture SiC substrates) use this type of substrate. However, the higher cost and limited availability of 6 inch SiC material means that the majority of LED producers use sapphire. WebBackgrinding Wax Adhesive Solutions for SiC, Sapphire and GaAs Wafers AIT wax film adhesives maintain more than 1000 psi shear bonding strength. The ability to hold the high shear bond strength up to 60 º C is important when backgrinding hard substrate wafers such as SiC (silicon carbide).
