1. :: It is highly questionable whether the patents describe monolithic integrated circuits . 2. The system used monolithic integrated circuits with magnetic thin-film memory. 3. These are readily manufactured by using the technology of either monolithic integrated circuits or hybrid integrated circuits. 4. Like the 70 / 45, the Model 70 / 55 made extensive use of monolithic integrated circuits . 5. By the mid-1960s, the planar process has become the main technology of producing transistors and monolithic integrated circuits . 6. Kilby built the first circuit and filed for the first patent : the monolithic integrated circuit , or microchip. 7. The 70 / 45 was one of the first computer systems to use monolithic integrated circuits in its construction. 8. Kilby built the first circuit in 1958 and filed for the first patent : the monolithic integrated circuit , or microchip. 9. The first operational device was tested in September 27, 1960 this was the first planar and monolithic integrated circuit . 10. Input and output units followed at $ 1.55 billion, while digital monolithic integrated circuits placed fourth at $ 1.34 billion.
