What is UV Cameras in Semiconductor Manufacturing about?
UV cameras are used in several applications during semiconductor microchip manufacturing to detect defects that are invisible to the human eye. They utilize light in the 190-400nm UV range, which can reveal surface irregularities as small as 30nm. Key applications include inspecting bare silicon wafers for contamination, detecting pattern imperfections on patterned wafers, ensuring accurate photomask alignment, and monitoring wafer bonding processes. When selecting a UV camera, factors like quantum efficien
