WebA good BJT satisfies the following ; 7 Actual BJT Cross Section. Vertical npn sandwich (pnp is usually a lateral structure) n buried layout is a low resistance contact to collector ; Base width determined by vertical distance between emitter diffusion and base diffusion ; 8 BJT Layout. Emitter area most important layout parameter 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 … greenway ford orlando inventory
