Abstract:
Provided is a wafer boat having a plurality of SiC wafers mounted on the water boat so that main surfaces of the plurality of the SiC wafers vertically face each other. The wafer boat includes a wafer support member in which a plurality of wafer shelves supporting the plurality of the SiC wafers are provided along an arrangement direction of the plurality of the SiC wafers, and a surface roughness of at least the wafer support member is equal to or larger than 2 μm and equal to or smaller than 4 μm at Ra value.

Claim (Index 3):
A method of manufacturing the wafer boat according to  claim 1 , comprising:\n preparing an untreated wafer boat whose surface roughness is approximately 0.5 to 1 \u03bcm at Ra value; and wholly immersing the untreated wafer boat in dilute hydrofluoric acid having a concentration of 5 to 20 % or royal water.
