V
oltage
measurement
may
have
some
error
because
of
the
eects
of
the
cable
resistance
when
forcing
a
large
current.
T

solve
this
problem:
Use
K

connections
between
SMUs
and
DUT
.
T

cancel
the

connect
the
sense
line
as
close
as
possible
to

If

Causes
High
T
emperature
(Thermal
Drift)
If
a
large
current
is
forced
to
a
DUT
,
the
temperature
of
the
DUT
may
increase
,
which
may
cause
characteristics
to
drift.
T
o
solve
this
problem:
Use
the
pulse
output
mode
of
the
SMU
.
F
or
large
currents
,
the
SMU
should
be
set
to
pulse
output
mode
.
This
decreases
the
average
power
output
to
prevent
temperature
rise
of
DUT
.
