-Generally measured at 1 MHz (high frequency) or at variable frequencies between 1KHz to 1 MHz
-The dc bias VG is slowly varied to get quasi-continuous C-V characteristics
② C-V characteristics of MOS-capacitor on p- and n-type Si
The C-V data depends on the measurement frequency as well.
[Figure 11] Measured C-V characteristics on an P-type, N-
frequency change due to the added mass.[6–8] The induced cantilever stiffness change can produce a resonance frequency shift as high as the added mass, but increasing the microcantilever resonance frequency, depending on the attached protein density and thickness and the cantilever length.[9] Actually, this is one of the questions to be solved in order to avoid errors in the characterizatio
of SiO2 and silicon nitride Si3N4 at low conformity.
⇒ High growth speed up to 500 nm/min is possible.
∙ Deposit at low temperature because of plasma.
∙ High vacuum and taking long time.
⇒ Increase the temperature up to 250℃ despite of low temperature.
