Photo Shows How Computer Chips Were Made In 1975

…how do they get these impossibly complex designs into the processors? That leads us to the photo…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
