Research Abstract |
The stair-shaped I-V characteristics are obtained by inserting a stair-shaped gap between the gate and drain a metal-oxide-semiconductor field effect transis (MOSFET). The turn-on voltage depend on the amount of impurity ions along the path of punch-through. I-V characteristics of the poly silicon gate n-channel enhancement type MOS divide are complementary to those of the Al-gate p-channel MOS device with a similar structure. The stable step functional I-V characteristics are measured under a negative bias voltage applied to the substrate of boron deped p-Si.
