Abstract

1518957 Hall effect devices STANDARD TELEPHONES & CABLES Ltd 25 Nov 1975 48355/75 Heading H1K A Hall effect device comprises an n-type epitaxial Si layer 1 on a p-type Si substrate 2, the resistivity of the substrate 2 being at least 4 #cm. and at least four times that of the epitaxial layer 1. Silica layers 3 are situated on opposed major surfaces, and ohmic contacts 4 are made to the layer 1 through diffused n<SP>+</SP> region 5. The doner dopant in layer 1 is chosen to have a low diffusion coefficient so that it does not significantly penetrate the substrate 2 during growth of the layer 1.
