Abstract

PURPOSE:To recognize easily by an optical means whether a light shielding seal exists or not, by spreading black paint from the rear side of a transparent mount to make the mount opaque. CONSTITUTION:In order to shield a light, shale segments 3 are exfoliated from a mount 1 in the state where adhesive agent 2 is kept, and stuck on the window glass of an EPROM. At that time, the black paint 4 is spread on the rear side of the mount 1, and the mount 1 is made opaque. Therefore, in an automatic manufacturing process of semiconductor device, the check of automatic addition of the light shielding seal for EPROM is enabled, with a cheap and simple recognizing equipment which detects only on-off of the light. Thereby, it can be easily recognized by an optical means whether the light shielding seal exists or not.
