VTG BELL LABS WESTERN ELECTRIC WAFER PHOTO MASK GLASS 1980s TINY CIRCUIT BOARD

Description

Bell Labs Western Electric photo mask for integrated circuit wafer manufacturing. From the 1980’s as were many of the items from this collection. This item would look great framed and lit from behind. It is 5” by 7” in size. I have more of these and will be listing them as well. Some much larger. Will combine shipping.
This came from the estate of a retired Bell Labs engineer.
Bell Labs Western Electric Wafer Photo Mask Glass. Condition is very good overall. It looks like these were coated with some liquid that hardens. It looks like it was put on thinner in some areas. For parts or not working. This has been in storage for many years. It has minor scratches and the like on it from use but otherwise it looks great. NOTE: Also including a photo of the box label it came in with others however the box is NOT INCLUDED.
Shipped with USPS Priority Mail or similar.
