Title: Method for manufacturing electrical solid state devices utilizing shadow masking and ion-implantation

Abstract: The present invention describes the manufacture of a chip having a stratum in which a number of diffusions are spaced from each other by boundaries whose widths is the width of a gap. The diffusion on one side of a boundary is formed by ion bombardment, and that on the other side by heat transfer of ions of a material with which the film has been doped.
