What we have learnt
- Integration challenges often arise from interactions between multiple process steps.
- Real-time data and inline metrology are crucial for quick diagnostics and solutions.
- Collaboration among equipment, materials, and integration teams enhances success in addressing process integration issues.
Key Concepts
- -- Root Cause Analysis (RCA)
- A method used to identify the underlying reasons for faults or problems, focusing on solutions to eliminate the causes.
- -- Statistical Process Control (SPC)
- A statistical method of quality control that uses statistical methods to monitor and control a process.
- -- Conformal Barrier Layer
- A thin film coating that is uniformly applied to varying topography, crucial for improving adhesion and preventing delamination in semiconductor fabrication.
- -- Dry Cleaning
- A method used in semiconductor processing to clean surfaces with vapor or gas without the use of liquids, reducing surface tension and physical disruption.
