Sigma Circuits Inc history
Sigma Circuits Inc company history timeline
He started making the first commercial printed-circuit boards in 1943 for Technograph.
In 1952 Globe-Union (and, in particular, Jack Kilby) attended the famous Bell Labs symposium on transistor applications.
In October 1957 these eight engineers, fed up with his management, were introduced by a young New York investment banker, Arthur Rock, to the very rich Sherman Fairchild, a manufacturer of aerial cameras and small airplanes and, in particular, owner of Fairchild Camera and Instrument.
In March 1959 Jean Hoerni invented the planar process that enabled great precision in silicon components.
In 1959 Victor had also introduced the Electrowriter to transmit handwritten pages, the first major innovation since the telautograph.
The story was not any different in Britain, where in 1961 Ferranti developed its integrated circuits for the British navy.
The first electronic desktop calculator had been introduced in 1961 by Bell Punch in Britain, the ANITA MK, designed by Norbert Kitz, who had worked with Turing on the Pilot ACE, but it still used vacuum tubes.
In 1962 Signetics introduced its DTL ("Diode-Transistor Logic") product Utilogic, and Fairchild followed suite with the DTL 930.
In 1964 Jerry Luecke at Texas Instruments designed the TTL series 5400.
In 1966 Wang introduced a smaller machine based on the LOCI, the Wang 300, containing about 300 transistors.
CCC was purchased by Honeywell in 1966.
And there were the grandchildren, such as Electronic Arrays, founded in 1967 in Mountain View by Jim McMullen with people from General Microelectronics and Bunker Ramo.
Crowning this race to miniaturization, in 1967 Jack Kilby at T.I. developed the first hand-held calculator.
In 1968 Fairchild hired Tom Longo from Transitron to jumpstart their RAM business.
In 1968 the hypertext project run by Dutch-born Andries van Dam at Brown University, originally called Hypertext Editing System from the idea of his old Swarthmore College friend Ted Nelson, yielded the graphics-based hypertext system FRESS for the IBM 360.
Sanyo introduced the ICC-82D (Integrated Circuit Calculator), built using Sanyo's proprietary integrated circuits, in May 1970; and Sharp unveiled the EL-8 in December 1970 using again Rockwell integrated circuits
By the end of 1970 the Santa Clara Valley, home to five of the seven largest US semiconductor manufacturers (Fairchild Semiconductor, Intel, Signetics, Four Phase, Advanced Memory Systems), had become a major center of semiconductor technology.
And in 1975 Modicon would introduce the "284", the first PLC driven by a microprocessor.
