Mounting/Unmounting Samples
The UV-Release Tape dispenser is most-often used for mounting sample for dicing.
The Tape Model installed is XYZXYZ. 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).
- Choose a photoresist of appropriate thickness, and spin-coat it & soft-bake it according to a standard recipe. Contact Alignment PR Recipes Stepper PR Recipes
- Perform your dicing
- Strip the PR in Acetone and ISO & N2 dry
Wafer Bonder (Logitech WBS7)
This tool is used for bonding samples to Silicon carrier wafers with CrystalBond wax.
Wax Mounting Procedure, with Spin-On Crystalbond
Draft only - in progress. -- Demis 2018-10-16
- Mix a fresh squirt bottle of CrystalBond diluted with Acetone (see Don Freeborn for method).
- XYZ grams of crystalbond, mixed into
- XYZ mL of Acetone, in dedicated squirt bottle
- Shake/stir to completely dissolve the wax
- Place 4-inch silicon carrier wafer on POLOS spinner in solvent bench, with non-vacuum 4-inch chuck installed.
- Set up POLOS recipe
- Spin at XYZ rpm for XYZ sec.
- Squirt wax solution onto wafer
- I/O to spin.
- Place carrier wafer on Logitech bonder surface
- Place sample to be bonded on top
- Place 110mm chemical filter paper on top
- Close lid, secure lid clamp
- Run recipe:
- XYZ °C
- XYZ seconds
- Vacuum etc.?
