Abstract
A bipolar junction transistor preferably includes: an emitter region; a base region; and a collector region, in which an edge of the emitter region is aligned with an edge of the base region. Preferably, an edge of the base region is aligned with an edge of the collector region, the edge of the emitter region is aligned with the edges of the base region and the collector region, and the widths of the emitter region, the base region, and the collector region are equivalent. According to a top view of the bipolar junction transistor, each of the base region and the collector region includes a rectangle.
