Abstract:
Methods for fabricating coated semiconductor elements are presented. The methods include the steps of combining a phosphor of formula I and a polymer binder to form a composite material, providing a semiconductor wafer including IniGajAlkN, wherein 0≤i; 0≤j; 0≤k, and a sum of i, j and k is equal to 1, coating the composite material on a surface of the semiconductor wafer to form a coated semiconductor wafer, and dicing the coated semiconductor wafer using a cutting fluid apparatus to form one or more coated semiconductor elements. A cutting fluid of the cutting fluid apparatus includes a C1-C20 alcohol, a C1-C20 ketone, a C1-C20 acetate compound, acetic acid, oleic acid, carboxylic acid, a source of A, silicic acid, or a combination thereof.
