Abstract

1457586 Integrated circuit resistors TEXAS INSTRUMENTS Ltd 20 March 1974 12299/74 Heading H1K An integrated circuit includes a resistor comprising a first region 3 of semiconductor material of a first conductivity type in a second region 2 of a second type on a substrate 1 of the first type, a first terminal 15 for connection to a voltage of one polarity (the substrate 1 being connected to the opposite polarity) and in which parasitic transistor action is prevented and protection against incorrect polarity connection is afforded by a connection between the second region 2 and the terminal 15 through a further resistor region of the first type within the second region. As shown, the two resistor regions are contiguous to the left and right of the terminal 15, although they may be formed as separate regions within the region 2. One end of the resistor is connected by metallization 9 to the collector of an NPN transistor 21, 19, 17 and one end of the protective resistor region is shorted by metallization 8 to the region 2. During normal operation the region 2 and substrate 1 form a reverse biased PN junction and the right hand part of region 3 passes no current. If the power supply polarity is incorrectly connected this PN junction conducts but the current is limited by the resistance of the region 3 between terminals 8, 15 which is chosen to keep heating low enough to prevent damage.
