E. Simoen et C. Claeys, THE USE OF BODY TIES IN PARTIALLY DEPLETED SOI MOSTS OPERATING AT CRYOGENIC TEMPERATURES, Solid-state electronics, 37(12), 1994, pp. 1933-1936
In this paper, the use of a body tie in partially depleted SOI MOSTs o
perating at 4.2 K is critically discussed. It is shown that there is a
considerable improvement in the threshold voltage metastability and t
he related hysteresis and transient behavior of the drain current. How
ever, the typical floating body effects, like the kink and the parasit
ic bipolar action are hardly suppressed. This is mainly due to the hig
h series resistance of the body contact, similar as in bulk MOSTs oper
ated at liquid helium temperatures.
