Abstract: An orthogonal bipolar transistor structure is disclosed which is particularly suitable for formation in relatively thin epitaxial layers on insulating substrates. The emitter of the transistor is disposed directly over the base region while a collector region may be arranged on one side of or surrounding the base region. Alternatively, the collector region may be a pair of regions disposed laterally on opposite sides of the base region.
Abstract: The present invention sets forth an integrated circuit (IC) device wherein the IC chip includes peripheral circuits, such as input/output circuits, which are arranged non-perpendicular with respect to the rectangular shape of the active area of the IC. This structure permits positioning some of the terminal bond pads closely adjacent the corners of the chip without overlap of adjacent circuits.
Abstract: A PNP transistor and a current limiting resistor are formed in a single active region of an integrated circuit device. The resistor is arranged to limit current flow between the emitter and collector regions of the transistor upon breakdown of the PN junctions due to momentary high voltage.
