Classification: CPC H | IPC H

Claim 12:
13. The apparatus of claim 9, wherein the lateral NPN transistor is a first lateral NPN transistor, the collector implant is a first collector implant, the emitter implant is a first emitter implant, and the base implant is a first base implant,
the apparatus further comprising a second lateral NPN transistor including:
a second collector implant disposed in the semiconductor layer, the second collector implant being of n-type conductivity;
a second emitter implant disposed in the semiconductor layer, the second emitter implant being of n-type conductivity;
a second base implant disposed in the semiconductor layer adjacent to the emitter implant, the second base implant being of p-type conductivity; and
a second isolation trench disposed in the semiconductor layer in a base region of the second lateral NPN transistor, the second isolation trench being disposed between the second collector implant and the second emitter implant, and disposed between the second collector implant and the second base implant.
