Challenge Problems
Push your limits with challenges.
Question 1
In a different simulation where the growth rate is modified to 2 Å per cycle, how thick would the film be after 50 cycles?
💡 Hint: Use the formula thickness = cycles × growth rate.
Question 2
If the ALD process exhibits non-linear growth due to chemical reactions and the growth rate doubles after 100 cycles, what would the film thickness be after 150 cycles, assuming it started at 50 Å?
💡 Hint: Break down the calculations into segments based on growth rates.
