HISTORIC NOTES

The unique history of Fairchild Semiconductor and its pioneering devices has been documented in a variety of sources. The initial product line of this company, developed shortly after the founders departed as a group from Shockley Transistor Corporation in 1957, was a high performance silicon mesa transistor. Initial shipments were made to IBM in 1958 for use as a memory core driver ($200 for each transistor). By 1958, Fairchild began marketing the transistor commercially as the 2N697. These were the best performing silicon transistors available at the time, and were very successful commercially. Other semiconductors companies quickly joined in, and the 2N697 (and its related cousins, the 2N696, 2N1131 and 2N1132) soon became commonly available and were produced for many years by many companies. Early prices were quite high and made substantial profit for those companies capable of silicon transistor manufacturing. Texas Instruments, for example, offered the 2N697 for $28.50 each in the 1960 Lafayette radio catalog. (Note: the earliest Fairchild devices are easily identified by the stylized F stamped in the top of the metal case, as in the example shown in the photo above).
