Abstract

1,211,498. Electroluminescence. STANDARD TELEPHONES & CABLES Ltd. 5 March, 1969, No. 11779/69, Heading C4S. [Also in Divisions H1 and H3] A light-emitting PN junction is connected in series with or forms one of the end junctions of a four-layer switching diode. A bias suitable for light emission is applied to the combination but is blocked by the four-layer diode which may be triggered into conduction by a voltage pulse to initiate light emission. The arrangement may be switched off by removing the bias or by applying a pulse of opposite polarity. Each of an array of GaAs, GaP, or GaAsP light-emitting diodes encapsulated in a lens may be connected in series with a silicon four-layer diode, Figs. 2 and 3 (not shown). Composite integrated circuit arrays with an intrinsic memory may also be constructed, in a first embodiment of which; Figs. 4 and 5 (not shown), an N-type silicon substrate (40) is processed to form P, N and P type layers (41, 42, 43) on one face, a metal layer (44) is formed in ohmic contact with the upper P type layer (43), and layers (45, 47) of N and P type GaAsP are formed on the metal layer. A grid of slots (48) is formed by sawing, etching or air abrading through the layers on the substrate to form the array, an ohmic contact (49) is applied to the lower face of the substrate and individual electrodes (50) having apertures for light emission are provided on the top of each device of the array. The grooves may be filled with insulating material such as epoxy resin and the upper electrodes provided with connections in the form of evaporated strips or by connecting wires. Limiting resistances (52) may be resistive tracks on a printed circuit board. In modification, Figs., 7 and 8 (not shown), a resistive layer (72) is provided between the Si substrate (73) and the lower electrode (71) which is mounted on an insulating member (70). The grid of slots is deeper in this case, the slots parallel to one direction extending through the whole thickness of the device including the lower electrode while the slots normal to that direction extend through the semi-conductor layers and the resistive layer but not through the lower electrode. The wafer is thus divided into an array of individual devices each row being mounted on a common lower electrode strip. The electrodes applied to the upper surface are in the form of strips normal to the lower strips to form co-ordinate addressing connections. Resistive layers (72) and (92) (Fig. 9, not shown) function as current limiting resistances and also as capacitors for the short turn on or turn off forward or reverse voltage pulse so that the pulses are not blocked. The four-layer diodes of either arrangement may be of GaAs, GaP or GaAsP in which case the upper junction can emit light so that the separate light-emitting diode layers may be omitted, Figs. 6 and 7 (not shown). Alphanumeric displays and use with photographic film is disclosed.
