WebApr 8, 2024 · A transistor is a semiconductor device, which is formed by fusing two junction diodes. When the anodes of the two diodes are fused, the transistor is called an n-p-n transistor. When the cathodes of the two diodes are fused, the transistor is called a p-n-p transistor. A transistor consists of three parts – a collector, an emitter and a base. WebThe P+ region isolates multiple transistors in a single die. An aluminum metallization layer (not shown) interconnects multiple transistors and other components. The emitter region is heavily doped, N+ compared to the base and collector to improve emitter efficiency. Discrete PNP transistors are almost as high quality as the NPN counterpart.
