摘要： A mask inspection apparatus includes a booth, a carrier, two linear scanners, a light source module and a control unit. The booth includes a platform including a slot. The carrier is movable along the slot. The carrier includes a support face for supporting the mask, guiding elements on the support face, and an inspection window in the support face. The support face extends above the platform. The linear image scanners are vertically movable respectively blow and above the platform. The light source module includes two light boxes on the platform. The light boxes are operable to cast light on an upper face of the mask in an upper position. The light boxes are operable to cast light on a lower face of the mask in a lower position. The control unit is electrically connected to the carrier, the linear image scanner and the light source module.
