Abstract
An integrated circuit device is provided in which an I.sup.2 L element and linear transistor are formed on a single chip such that they coexist. In this device, the base and collector regions of a vertical transistor of the I.sup.2 L element are formed such that they are deeper than the base and emitter regions of the linear transistor.
