Advanced Photolithography and Patterning

Students will master the principles, equipment, and practical applications of modern lithography, including DUV, EUV, and alternative patterning methods. The course covers resist chemistry, metrology, defect inspection, and process integration for sub-nanometer feature fabrication. Emphasis is placed on problem-solving in an online, technical institute context, preparing students for advanced roles in the semiconductor industry. Real-world case studies and virtual simulations enhance practical understanding.

Syllabus

Each week features online lectures, readings, and virtual lab simulations or problem sets. Assignments are due Sunday evenings, and a weekly online discussion forum encourages peer interaction and concept reinforcement. Two midterms and a final project will assess understanding of advanced topics and practical application skills. Late submissions will incur penalties, though accommodations can be made for documented emergencies. Active participation in discussions and completing all assignments is essential for success in this challenging course. Students are expected to dedicate 12-15 hours per week to course materials and assignments.
