Start

Calculates Vbase

Sets meas. parameters

to I_sub sampling test

I_sub sampling meas.

by applying Vg pulse

Records Isub and Vbase

More Vbase?

Calculates IcpMax & NSS

Plots Icp vs Vbase

Looping of classic test for each

base step of Gate pulse.

Charge Pumping

Icp is measured after each increment of the gate pulse base value. A curve of Icp vs base value is

plotted. The maximum Icp value is noted. At this point:

Icp = f * Qss

= f * Ag * q * Dit

where

f: pulse frequency

Qss: recombined charge per pulse period

Aq: channel area of the transistor

q: electron charge

Dit: interface state density
