True. Some of these computers used hybrid integrated circuits (e.g. IBM System/360) and some used monolithic integrated circuits (e.g. Apollo Guidance Computer, Minuteman II Guidance Computer)

1958, but the germanium based process was difficult and expensive to use, requiring all the components in the IC be interconnected by hand under a microscope. It took another year or so for the silicon based planar process to be used, which allowed all components and interconnects to be made using photolithography.
You cannot discover something that does not exist - the principle of integrated circuits was first suggested and proven in 1958 by Jack Kilby working for Texas Instruments.

Kilby at TI did the first one using Germanium for his chips. The only thing not integrated was the wiring. The next year workers at Fairchild used Silicon and integrated everything.
The first generation used vacuum tubes, the second used transistors, the third used integrated circuits, and the fourth used integrated circuits on a single computer chip.
Both hybrid integrated circuits and monolithic integrated circuits were used in third generation computers. These integrated circuits contained from 4 to 100 transistors per integrated circuit. The image above shows hybrid integrated circuits of the type used in the IBM System 360 line of computers.

The first integrated circuit (see image above) was a germanium bar containing a simple amplifier circuit. It was made and tested in a research lab at Texas Instruments in 1958.
