I. Schonstein et al., CHARACTERIZATION OF SUBMICRON NMOS DEVICES DUE TO VISIBLE-LIGHT EMISSION, Microelectronic engineering, 21(1-4), 1993, pp. 363-366
In this paper process characterization by light emission of NMOS devic
es is discussed. Electrical measurements, optical measurements and sim
ulation results of conventional and LDD short channel transistors are
compared. As an application of the optical investigations, the control
able operating region and the effective channel length of NMOS transis
tors can be determined.
