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.

• Procedure for mounting sample on UV-Release Tape
• Full Release: 60 sec exposure
• Partial Release for Shipping: 9 sec exposure

Surface Protection

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.

   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

Wafer Bonder (Logitech WBS7)

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