ABSTRACT:
An electrical contact formed in a groove in the surface of a semiconductor material facilitates an advantageous contact with the material for a given cross-sectional area of contact when compared with a contact of the same cross-sectional area formed on the surface of the material. The grooved contact significantly reduces shading of the surface of the semiconductor material compared with an equivalent surface contact.
