INSPECTION DEVICE AND INSPECTION METHOD
Document Type and Number:
WIPO Patent Application WO/2020/085205
Kind Code:
A1
Abstract:
This inspection device is for inspecting devices to be inspected. The devices to be inspected are formed on an object to be inspected, and are backlit image-capture devices upon which light is incident from the rear side, which is the reverse side from the side on which a wiring layer is provided. The inspection device has a loading platform on which is placed the object to be inspected in a state in which the rear surfaces of the image-capture devices face the loading platform. The loading platform comprises: a light-transmissive portion which includes a plate-shaped plate member made from a light-transmissive material, and upon which the object to be inspected is placed; and a light-emitting portion which is disposed in a position facing the object to be inspected with the light-transmissive portion interposed therebetween, and which emits light towards the light-transmissive portion. The light-transmissive portion allows the passage of light emitted from the light-emitting portion while diffusing said light.
