Rj. Schreutelkamp et L. Deferm, A NEW METHOD FOR MEASURING THE SATURATION VELOCITY OF SUBMICRON CMOS TRANSISTORS, Solid-state electronics, 38(4), 1995, pp. 791-793
A method is presented to extract the saturation velocity upsilon(sat)
of charge carriers in the inversion channel of submicron length CMOS d
evices. The method is more reliable than those available from literatu
re since series resistance effects are included in the formulary. For
surface channel NMOS transistors, a saturation velocity of upsilon(sat
) = 6.9(+/- 0.5) x 10(6) cm/S was measured while for surface (p-type p
oly-Si) and buried (n-type poly-Si) channel PMOS transistors upsilon(s
at) = 4.5(+/- 0.5) x 10(6) and 6.0(+/- 0.5) x 10(6) Cm/s, respectively
, was found.
