Resulting resist thickness can be determined as y = axb+c, where y is thickness [nm], x is spin speed [RPM], a = 65274, b = -0.748 and c = 163.1.
Contrast curve
A contrast curve for AR-P 617.06 is provided below based on exposure at 100 kV for doses from 2.5 to 200 µC/cm2. The dose clear is dependent on softbake temperature, in this case either 200C or 180C is used. Process parameters are:
- Date: January 30th 2024
- Coater: LabSpin 2
- Substrate: 2" Si
- Acceleration: 1000 RPM/s
- Time: 60 s
- Baking temperature: 200C and 180C
- Baking time: 120 s
- Exposure: 100 kV (JEOL 9500)
- Development: AR 600-50 for 60 seconds
- Stopper: IPA for 30 seconds + blow dry with nitrogen
