Abstract
1,245,668. Semi-conductor devices. ITT INDUSTRIES Inc. 23 April, 1969 [2 May, 1968], No. 20659/69. Addition to 1,230,879. Heading H1K. [Also in Division H3] Fine control of the temperature compensation of a simulated Zener diode structure of the kind described in the parent Specification is obtained by means of an additional transistor structure having its collector formed in the common collector zone and having a first resistor connecting its emitter to its base and a second resistor connected to its base, the emitter and the end of the second resistor remote from the base forming terminals which are inserted at some point in the series chain of forward and reverse biased emitter junctions, one of the resistors being adjusted by means of an at least partial short circuit. As shown, Fig. 2, a plurality of transistor structures, some of which have double emitters, are formed with a common collector region and are connected so that their emitters form a plurality of reverse biased Zener junctions in series with a plurality of forward biased junctions to provide temperature compensation. An additional transistor structure T is provided together with resistors R 1 and R 2 which are inserted into the series circuit. Resistor R 2 is adjustable and this is achieved by depositing a layer of metal over it during the manufacture of the device to provide a short circuit, measuring the temperature coefficient of the completed device and selectively removing parts of the metal layer short circuiting R 2 to provide the fine adjustment of temperature coefficient. The resistors may be formed as diffused regions arranged in the common collector zone, or as resistive tracks on the surface. Reference has been directed by the Comptroller to Specification 1,082,519.
