Abstract
A superlattice of LT-GaAs layers and another semiconductor layers such as LT-AlGaAs or HT-GaAs is grown on a substrate. Lattice imperfectness such as strain or crystal defects is selectively introduced. Then, the superlattice is annealed to produce As precipitates at selected locations of the LT-GaAs layers. When strain is given by metal electrodes, anisotropic etching and self-alined metal deposition can be done utilizing these electrodes. Various semiconductor devices, particularly SET device can be manufactured utilizing those metallic precipitates.
