djena.engineering.cornell.eduone. A transistor with epitaxial layer added was reported in 1960. In the same year Jean Hoerni proposed the pla-nar transistor (both base and emitter regions diffused). The oxide that served as a mask was not removed and acted as apassivatinglayer[15]. Further improvement of speed was proposed by Herbert Kroemer.

The EPI layer is doped appropriately for the best transistor performance (more lightly doped than the remaining lower portion of the substrate that is highly doped). The highly doped substrate directs majority carriers to ground and reflects minority carriers making the guard rings more effective (see Figure 3).
