Abstract

See full text

A bipolar transistor includes a substrate having a first well with a first dopant type; and a split collector region in the substrate, the split collector region including a highly doped central region having the first dopant type, and a lightly doped peripheral region having a second dopant type, opposite the first dopant type, wherein the lightly doped peripheral region surrounds the highly doped central region, a dopant concentration of the lightly doped peripheral region ranges from about 5×1012 ions/cm3 to about 5×1013 ions/cm3, and the lightly doped peripheral region has a same maximum depth as the highly doped central region.
