A seed crystal for aluminium nitride (ALN) crystal growth relates to a material for ALN crystal growth. A problem that spontaneous nucleation adopted at current is difficult to obtain a big-size ALN crystal and an impurity content of the ALN crystal grown by an alloplasm seed crystal method is high is solved. The seed crystal for ALN crystal growth is an ALN ceramic wafer after treatment of annealing process. The seed crystal for ALN crystal growth further can be an ALN ceramic wafer after treatment of annealing process and polishing in sequence, or an ALN thin film is pasted on the surface of a polished seed crystal to obtain the seed crystal for ALN crystal growth. The ALN crystal grown by using the seed crystal for ALN crystal growth is big in size and fewer in impurity content. The seed crystal is mainly applied to growth of the ALN crystal in a semiconductor device.
