Abstract:
A semiconductor component, comprising:a substrate; only one epitaxial layer disposed on said substrate; at least a first bipolar component and a second bipolar component integrated in said epitaxial layer; said first bipolar component having: a first buried layer having: dopant in a first dopant concentration; and a first buried layer thickness; a substance influencing diffusion of said dopant in said first buried layer, said substance having a given concentration; and a first collector with a first collector width; said second bipolar component having: a second buried layer having: dopant in a second dopant concentration substantially identical to said first dopant concentration; a second buried layer thickness larger than said first buried layer thickness; and a substance influencing diffusion of dopant in said second buried layer, said substance having a concentration different from said given concentration; and a second collector with a second collector width different from said first collector width.
