3.3

Special Handling of Dice: Rad Hard dice require special handling as compared to standard IC dice.

Rad Hard dice are susceptible to surface damage due to the absence of silicon nitride passivation that is

present on most standard dice. Silicon nitride protects the dice surface from scratches by its hard and

dense properties. The passivation on Linear Technology’s Rad Hard dice is silicon dioxide which is

much “softer” than silicon nitride. . During the visual and preparation for shipment, ESD safe Tweezers

are used and only the edge of the die are touched.

LTC recommends that dice handling be performed with extreme care so as to protect the die surface

from scratches. If the need arises to move the die in or out of the chip shipment tray (waffle pack), use

an ESD-Safe-Plastic-tipped Bent Metal Vacuum Probe, preferably .020” OD x .010” ID (for use with

tiny parts). The wand should be compatible with continuous air vacuums. The tip material should be

static dissipative Delrin (or equivalent) plastic.

During die attach, care must be exercised to ensure no tweezers, or other equipment, touch the top of

the dice.
