Handling precautions
for
the
prevention
of
electrostatic destruction
Explained below are procedures
that
must
be taken
in
fabrication
to
prevent
the
electrostatic destruction
of
semiconductor
devices.
The
following basic
rules
must
be obeyed.
©Equalize
potentials
of
terminals
when
tran-
sporting or
storing.
©Equalize
the
potentials of
the
electric
device,
work
bench,
and
operator's
body
that
may
come
in
contact with
the semi-
conductor
device,
©Prepare
an environment
that
does
not
generate
static
electricity.
One method
is
keeping
relative
humidity
in
the
work
room
to
about
50%.

Clothes
Do
not use
nylon, rubber
and
other mate-
rials
which
easily
generate
static electricity.
For
clothes,
use
cotton, or antistatic-treated
materials.
Wear
gloves during
operation.

Grounding
of operator's
body
The
operator should connect the
specified
wrist strap
to his
arm.

When
using a copper
wire for

Handling
of
semiconductor device
Do
not
touch
the
lead.
Touch
the
body
of
the
semiconductor
device
when
holding.
Limit the
number
of
handling times
to a
minimum. Do
not take
the device out
of the
magazine
or
package
box
unless
it
is
abso-
lutely
necessary.
