======The Heidelberg====== {{::heidelberg_user_guide.pdf|Heidelberg User Guide}} {{::upg101_ug8_design_guide.pdf|Heidelberg Design Guide}} ======Best Practices====== 1. when preparing small samples, run them for 2-5 seconds at 6000 rpm to get even photoresist at the edges. 2. Negative photoresist creates a hole when exposed. (S1805 noninverted) 3. Positive photoresist creates a mountain when exposed. (S1805 inverted) 4. Create small inversion boxes in your mask pattern to define the exact size you want. A full 10x15mm sample should take 1 hour to write maximum. ======User Exposure Recipes====== ==================== ==HIMT KQ (Kamran) (4/6/2016)== ==================== Substrate: Al+lithium niobate --> Whole wafer Adhesion Promotor: HDMS (3000 rpm 8 sec) Resist: S1805 (3000 rpm 30 sec) Bake: 100°C in the oven for 15 min WM I (4mm): Filter: ON Energy: 10 mW 42% (%1 to %34 doesn't work well.
