alloy junction การใช้

General Electric pioneered the alloy junction transistor process for germanium transistors.
The 2N43-45 series was GE's first commercial alloy junction transistor using the 2N numbering system.
Like Raytheon's CK722, the GE 2N107 were fallouts or rejects of GE's successful 2N43, 2N44 and 2N45 alloy junction transistors.
In the 1950s, the emitters and collectors of n-p-n alloy junction transistors were doped with tiny beads of a lead-antimony alloy.
Raytheon quickly moved into alloy junction transistor because of the lower noise, more rugged and lend it self to mass production, compared to point contact transistor.
