Abstract
1,259,212. Electroluminescence. INTERNATIONAL BUSINESS MACHINES CORP. 30 June, 1969 [1 July, 1968], No. 32969/69. Heading C4S. [Also in Division H1] Electrical contact to a region of one conductivity type defining an electro-optically active junction in a body of the opposite conductivity type is achieved by means of a pin mounted in a bore passing into the region from a planar face of the body, the pin extending out of the body at the face. The device may be a photovoltaic detector or a photo-emissive diode or laser. The light emission or reception occurs at a second planar face so that the light path is not blocked by the contact to the region. An N-type body 23<SP>1</SP> contains an array of devices 22 each comprising a P-type region 27 contacted by a pin 28 which is a tight fit in a bore 25 to provide a pressure contact, Fig. 5. In modifications the pin extends to the top surface of the wafer where it is provided with a head of such dimensions that the light path is not blocked, Fig. 6 (not shown), a headed pin is soldered into the bore, Fig. 7 (not shown), and a wire is soldered in the bore, Fig. 8 (not shown). The PN junction shape may be inverted relative to that shown or may comprise a straight cylinder, Fig. 17 (not shown), and the bore may extend halfway only through the body, Figs. 9b and d (not shown). If the pin is provided with a head this may be of transparent material. The junction may be so arranged that the light is emitted from the edge of the body, Fig. 18 (not shown). The devices are made by forming the bore in the body by masking and etching or by electron beam drilling, and then photomasking and diffusing to form the region surrounding the bore. The starting body may comprise an epitaxial layer on a substrate of the same conductivity type. The surface through which the light passes may be lapped or polished to improve the light transmission and the face through which the contact pins extend may be coated with an opaque material such as beryllium oxide or boron nitride. The semi-conductor material may be GaAs, or GaAlAs utilizing Te and Zn as the N- and P-type impurities.
