Photo Shows How Computer Chips Were Made In 1975

Here is a blast from the pastآ—a Motorola engineer looks at masks for chip engraving all the way back in 1975. These could actually make for some pretty cool abstract art for bare walls.

آ…how do they get these impossibly complex designs into the processors? That leads us to the photoآ…featuring a Motorola engineer in the 1970s, taking a close look at the drawn transistors of a computer chip. These sheets, all color-coded, would soon be printed onto a piece of silicon, giving a tightly-wound processor more computing ability than one could ever get from a printed circuit board on its own. A major innovation came about in the computing space roughly a decade prior, when it was realized that transistors could be drawn into complex integrated circuits.
