Description: ~ Rare Glass IC Mask ~Made by Signetics Was used in the manufacturing of integrated circuits.This is not a silicon wafer, but a mask used to focus light onto a silicon wafer. It measures 2.5” by 2.5”. Signetics was a pioneer in IC design in the early 60’s and 70’s before being absorbed by the larger manufacturer Philips Semiconductor. Signetics was responsible for several best selling IC’s including the 555 timer. “Signetics Integrated Circuits” is printed on the bottom right (See photos). The Signetics company Logo is also visible. All images shown are from this glass mask. From Wikipedia:“Signetics was the first electronics manufacturer specifically established to make integrated circuits. Founded in 1961, they went on to develop a number of early microprocessors and support chips, as well as the widely used 555 timer chip. They were bought by Philips in 1975 and incorporated in Philips Semiconductors (now NXP).” Own a piece of early IC history! This durable glass IC mask is suitable for display.
