Granted: 2003-03-11
Abstract: A crystal foundation with dislocations is used to obtain a crystal film of low dislocation density, a crystal substrate, and a semiconductor device. One side of a growth substrate (11) is provided with a crystal layer (13) via a buffer layer (12). The crystal layer (13) has spaces (13a), (13b) in the terminal of each dislocation D1 elongating from below. The dislocation D1 is separated from the upper layer by the spaces (13a), (13b), so that each dislocation D1 is blocked from propagating to the upper layer. When the displacement of the dislocation D1 expressed by vergarse vector is preserved to develop another dislocation, the spaces (13a), (13b) vary the direction of its displacement. As a result, the upper layer above the spaces (13a), (13b) turns crystalline with a low dislocation density.
