Abstract

1295530 Electroluminescence WESTERN ELECTRIC CO Inc 23 June 1970 [23 June 1969] 30336/70 Heading C4S [Also in Division H1] A GaP electroluminescent device includes a diode with two major faces parallel to P-N junction and electrical contacts on same, one comprising an SiO 2 layer 23 covering at least 75% but not all the major surface and a metal layer 25, preferably gold with 1 to 4% Si when the one major face is N-type, contacting substantially the remainder of the surface and extending over substantially all the SiO 2 . A support 27 is bonded to the diode and has a metallized portion 26 in contact with the metal layer. Preferably the other contact is Zn-Au alloy. The effects of contact optical absorption are considered, Fig. 1 (not shown) illustrating optical output efficiency as a function of absorbing contact area, and free carrier concentrations instanced are 5 x 107 to 4 Î 1018, e.g. 8 x 1017, and resistivities 0À07 to 0À10 # cm. for N-type and 0À08 to 0À12 # cm. for P-type. The design is stated to reduce optical loss and electric current nonuniformity without significantly increasing thermal impedance. Reference is made to Zn, Cd, Be, Mg, Ge dopants for P-type contacts and S, Se, Te, Si and Sn for N-type contacts, butane stated as unacceptable in practice. A 0À2 Á SiO 2 layer (23) (Figs. 2A to 2E, not shown) may be obtained by thermal decomposition of ethyl silicate at 650‹ C., or from evaporation of quartz by electrons, holes (24) etched, Au -2% Si layer (25) evaporated and alloyed, grooves (26) scribed, and the devices separated by sawing or cleaving, preferably assisted by etching which effects rounding the top edges to enhance optical efficiency. Layer 25 is bonded to circuit portion (26) of a printed circuit board. The P-side contact is a Au-Zn wire (28).
