NOVELTY - This new type utility claims one growing a large area of graphene device, comprising metal substrate, rolling boat, fixing device and diffusion furnace, metal substrate of two edge each set with at least one a small hole, said fixing device comprising fixing silk, a fixing silk passes through the two edge holes of the metal substrate fixed in the quartz boat rolled up. This utility new type scroll quartz boat for use as copper foil bearing device, the copper foil roll is assembled on the boat outer surface, then using only fixed silk fixing, it can maxinum the area of copper foil assembly and deposition, the copper foil roll always giving support boat is deposited on the sampling, sampling time would not produce folds, so it is not only area industrial production and laboratory experiment sample is much larger (can be more than 0.5m2), number uniform layer (1 to 3 layer), resistance and transmission uniformity, and large area graphene so the sample rear surface is smooth and flat without folding.
