2. Design and Implement Microfabrication Processes
Microfabrication processes involve a detailed sequence of steps to convert raw semiconductor wafers into functional devices, emphasizing substrate preparation, film deposition, patterning, etching, doping, and packaging. Key techniques such as thin film deposition and advanced lithography are critical as the industry advances towards smaller feature sizes. Yield optimization and integration of emerging techniques are essential for meeting modern fabrication requirements.
