TRENCH ISOLATION
In the ADG5433/ADG5434, an insulating oxide layer (trench)
is placed between the NMOS and the PMOS transistors of each
CMOS switch. Parasitic junctions, which occur between the
transistors in junction isolated switches, are eliminated, and the
result is a completely latch-up proof switch.
In junction isolation, the N and P wells of the PMOS and
NMOS transistors form a diode that is reverse-biased under
normal operation. However, during overvoltage conditions, this
diode can become forward-biased. A silicon controlled rectifier
(SCR) type circuit is formed by the two transistors causing a
significant amplification of the current that, in turn, leads to
latch-up. With trench isolation, this diode is removed, and the
result is a latch-up proof switch.
