3. Lithography (Photolithography).zip
Photolithography is a patterning technique used to transfer intricate circuit designs onto the surface of a semiconductor wafer. It uses ultraviolet (UV) light to selectively expose a light-sensitive chemical called photoresist, allowing precise formation of micro- and nano-scale features on the wafer.
Photolithography is a critical patterning step where accuracy and precision directly impact device functionality. It is essential to distinguish between well-executed (good) and defect-prone (not good) photoresist patterns.
-
Well-defined, straight photoresist lines and patterns
-
High edge sharpness
-
Uniform resist thickness
Defective photolithography results in inaccurate pattern transfer, which can cause short circuits, open circuits, or misaligned features.
-
Blurred or distorted resist lines
-
Misalignment
-
Undercutting or footing
