Diffused junction transistor

A diffused junction transistor is a transistor formed by diffusing dopants into a semiconductor substrate. The diffusion process was developed later than the alloy junction and grown junction processes for making bipolar junction transistors (BJTs). Bell Labs developed the first prototype diffused junction bipolar transistors in 1954.
