Description
The fully automated DWL 66+ laser writing system is located inside an environment chamber for stable environment of the system with controlled laminar airflow and temperature stability. The chamber is situated on a granite base with air cushions for vibration isolation. The optical system includes highly reflective mirrors and acousto-optic modulators for real-time beam correction.
Lens & Resolution
- 2 mm lens (optical autofocus): 600 nm
- 10 mm lens (pneumatic autofocus): 2 µm
- 40 mm lens (pneumatic autofocus): 10 µm
Applications
- Patterning of photomasks
- Direct laser writing of patterns
Processes
The following exposure parameters may be used to expose photomasks.
| Resist | Write Head | Filter(s) | Laser Power (mW) | Intensity | Focus | # of passes | Focus mode |
|---|---|---|---|---|---|---|---|
| AZ1500 | 10mm | 25% | 60 | 60% | -20 | 1 | Pneumatic |
| IP3500 | 10mm | 50% | 60 | 50% | -20 | 1 | Pneumatic |
| IP3500 | 2mm | 25% & 12.5% | 60 | 50% | 0 | 1 | Pneumatic |
The following exposure parameters may be used to direct write into S1800 resist (soft baked at 115C for 1 minute) on silicon. For the optimum focus, please refer to the "AZ1500.txt" or "IP3500.txt" files for the optimum value to use.
| Resist | Spin Speed (RPM) | Write Head | Filter(s) | Laser Power (mW) | Intensity | # passes | Focus mode |
|---|---|---|---|---|---|---|---|
| S1805 | 3000 | 10mm | 25% | 35 | 60% | 1 | pneumatic |
| S1805 | 3000 | 2mm | 1% & 50% | 105 | 100% | 1 | pneumatic |
| KL5315 | 5000 | 10mm | 50% | 35 | 70% | 1 | pneumatic |
| KL5315 | 5000 | 2mm | 1% | 75 | 100% | 1 | pneumatic |
| S1818 | 3000 | 10mm | 50% | 65 | 80% | 1 | pneumatic |
| S1818 | 3000 | 2mm | 12.5% & 25% | 60 | 60% | 1 | pneumatic |
