The d.c. characteristics are computed for pnp polysilicon emitter transistors (PETs) in which a thin insulating layer is incorporated in the emitter structure. Both devices with, and without, a post-polysilicon deposition annealing treatment are modeled. The effects of the annealing are taken to be a reduction in the insulator thickness and the creation of a p-type monosilicon emitter region. The simulations reveal that moderate current gains, around 300, are possible with these devices.
