WebThe vertical cross-section of a PT IGBT is shown in the figure. It has a p + substrate at the bottom. This forms a pn-junction with n – drift region. The conduction modulation in this junction occurs by injecting minority carriers into the n – drift region. The p + substrate, n – drift and the p + emitter together constitute a BJT. NPT IGBTs are known as symmetrical … WebConsider the NPN BJT made of silicon is in the forward active region, with lç = 10 JA, doping concentrations NE = 1018 cm-3, NB thicknesses WE = 0.5 µm, WB = 0.25 µm, and Wc = 2 µm; and diffusion constants DPE %3D 1017 cm3, and Nc = 1016 cm³3; %3D %3D = 20 cm2/s, and Dpc = 2 cm?/s, DnB cross-sectional area A = 1 um².
