In this video you'll learn the preferred KNI way to spin photoresist onto wafers and pieces using the KNI's Laurell brand spinners. You can learn more about using resists and lithography in the KNI on our Lab wiki, by visiting the Optical Lithography Resources page ([ Ссылка ]) and touring the Lithography Equipment ([ Ссылка ]). Also see the KNI's Spinner Rules ([ Ссылка ]), a written SOP on how to clean the spinners ([ Ссылка ]), and the Laurell Manuals (Lite Version: [ Ссылка ] & Long Version: [ Ссылка ]).
The video includes how to:
1. Select and verify a spin recipe (0:56)
2. Inspect and clean the spinner (1:40)
3. Spin-clean the wafer and pre-bake (2:37)
4. Prepare wafer surface with HMDS, if necessary (3:55)
5. Load wafer onto chuck, apply resist, and spin (4:55)
6. Remove resist edge bead (6:30)
7. Post-bake the wafer (7:22)
8. Clean the spinner (7:38)
9. Exchange in/out various vacuum chucks and adapters(9:23)
10. Spin resist onto a small piece (10:30)
11. Document the parameters of your run in the log book (13:07)
12. Replace a vacuum chuck or adapter o-ring, if necessary (13:50)
