Abstract

The invented method obtains a quality semiconductor crystal independent of the base substrate. The method comprises: forming a seed crystal layer formed of a GaN layer 103 (second layer of the seed crystal layer) and an AlN buffer layer 102 (second layer of the seed crystal layer) on a sapphire substrate 101; etching the surface of the seed crystal layer to form grooves having a width (width of the seed crystal S) of about 5 mum, a side wing width W of about 15 mum, a depth of about 0.5 mum, in order to form a rectangular platform with an approximately cross-sectioned shape; aligning the eroded remain portion of the flattened part having the seed crystal layer according to a period L of about 20 mum so that the side wing valley part exposes a portion of the sapphire substrate 101, in which the ratio of the width of the seed crystal to the side wing, S/W, is preferably 1/3; growing the semiconductor crystal A to be more than 50 mum; and separating the crystal from the base substrate to obtain a quality single crystal independent of the base substrate.
