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

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. Remove the die from the UV release tape
  3. Strip the PR from each die in Acetone and ISO & N2 dry
