Project Title
Enhancing Poly-SiGe Gap Fill Performance in High Aspect Ratio Structures for Improved Die Strength and Reduced Wafer/Dice Bending
Project Description
This project aims to improve Poly-SiGe gap filling in high aspect ratio (HAR) structures to enhance die strength and reduce block bending. The intern will study the impact of deposition conditions on film growth, conformality, and void formation, identify strategies to improve fill performance while minimizing early pinch-off, and correlate gap-fill characteristics with mechanical integrity.
The outcome will be a deeper understanding of the key mechanisms governing successful HAR feature filling and die-strength improvement.
Project Scope
Investigate effects of process parameters on fill depth and gap-fill in HAR structure
Identify process conditions that improve bottom-up fill while maintaining open feature entrances.
Identify critical fill characteristics that contribute most to structural robustness.
Recommend optimized window and qualification plan
Learning Opportunities
Gain hands-on application on material science and semiconductor integration.
Experience the end-to-end development cycle from problem definition to qualification proposal
Collaborate with cross-functional engineering teams and subject matter experts.
Deliverables
Quantitative comparison of voids, seams, and pinch-off behavior
DOE and experimental matrix with SEM/TEM cross-section analysis of filled structures.
Correlation between fill quality and die-strength/block-bending performance to recommend process window
Impact of Project
Enhances die strength and reduces block bending through improved feature-fill quality and stress management.
Provides a scalable process solution that can improve yield, reliability, and manufacturability for future technology nodes.
Skillsets Required
Strong analytical and problem-solving skills.
Familiarity with machine learning, statistical analysis, and AI-enabled workflows
Familiarity with semiconductor materials, thin-film deposition, process integration, or materials characterization.
Familiarity with Design of Experiments, statistical analysis, and interpretation of experimental data
Course of Interest:
