Dicing Saw Recipes (ADT 7100)

Recommended Dicing Parameters

This table is for our stocked Resnoid blades: -4C blades are 4mils/100µm wide, while -8C blades are 8mils/200µm wide. Plan for ~50–100µm extra edge clearance to account for chipping etc.

Narrower (~30-50µm) Nickel Hubbed blades are often used for even narrower dicing streets, these must be purchased by the user.

Mounting/Unmounting Samples

The UV-Release Tape dispenser is most-often used for mounting sample for dicing.

The Tape Model installed is Ultron 1042R. Data Sheet Here.

Surface Protection

Photoresist

Users most often use sacrificial photoresists to protect the surface from accumulating dicing dust. The static-buildup of dielectric films causes the dust to adhere strongly. Ensure that the PR thickness will adequately coat all your exposed topography (eg. use a ≥2µm thick PR for protecting 1.5-2.0µm tall etched features).

  1. Choose a photoresist of appropriate thickness, and spin-coat it & soft-bake it according to a standard recipe.
    1. Contact Alignment PR Recipes
    2. Stepper PR Recipes
  1. Perform your dicing
  2. Remove the die from the UV release tape (60sec UV Exposure)
  3. Strip the PR from each die in Acetone and ISO & N2 dry

Blue Tape

Alternatively our low-tack residue-free Blue tape can be used to protect the die surface. Blue tape removal is easy for large die, but does require manual removal from each die, and eliminates sample exposure to solvents.

The very edges of the die may accumulate a bit more dicing dust due to the tape delaminating slightly during dicing. Plan for about 50-100µm of edge clearance on each die.

Wafer Bonder (Logitech WBS7)

This tool is used for bonding samples to Silicon carrier wafers with CrystalBond wax.
