Abstract: An integrated circuit (100) includes high performance complementary bipolar NPN and PNP vertical transistors (10, 20). The NPN transistor is formed on a semiconductor substrate whose surface (24) is doped to form a PNP base region (28, 70). A film (32, 34, 30) is formed on the surface with an opening (42) over an edge of the base region. A first conductive spacer (48) is formed along a first sidewall (78) of the opening to define a PNP emitter region (67) within the base region. A second conductive spacer (47) is formed along a second sidewall (76) of the opening to define a PNP collector region (66).

Abstract: A structure and method of making an NPN heterojunction bipolar transistor (100) includes a semiconductor substrate (11) with a first region (82) containing a dopant (86) for forming a base region of the transistor. A second region (84) adjacent to the first region is used to form an emitter region of the transistor. An interstitial trapping material (81) reduces diffusion of dopants in the base region during subsequent thermal processing.

Abstract: A circuit and method protect a transistor (68, 70) from damage when controlling an input signal (V.sub.PROG) that exceeds a gate to channel stress voltage of the transistor. A small, low current protection transistor (64, 66) is serially coupled to the gate electrode of the transistor being protected. The gate of the protection transistor is biased to a voltage (V.sub.P, V.sub.N) of lower magnitude than the input signal to limit the voltage applied to the gate of the protected transistor to a value within the stress voltage of the protected transistor.
