In the fabrication of semiconductor devices, a method is provided which includes the steps of selectively doping a semiconductor substrate of one conductivity type to form therein discrete regions of opposite conductivity type, followed by selective epitaxial growth to fill the windows of the diffusion mask, whereby the epitaxially grown regions are inherently characterized by exact alignment with the doped regions. The self-aligned epitaxial structure is then subjected to further processing in accordance with numerous alternate schemes to provide a wide variety of devices.
