Challenge Problems
Push your limits with advanced challenges
You are tasked with fabricating a semiconductor with multiple layers. Discuss the trade-offs between achieving high selectivity during the etching process and the potential risk of damaging underlying layers. How would you approach this problem?
💡 Hint: Think about what etching parameters you can control to achieve selectivity.
Consider a scenario where uniform deposition is not achieved, leading to varying thicknesses across a wafer. Analyze how this can impact device performance and what methods might be employed to resolve this issue.
💡 Hint: Consider how deposition tools might be adjusted to improve uniformity in your response.
