摘要： In a high voltage integrated circuit, a low voltage region is separated from a high voltage region by a junction termination. A bipolar transistor in the high voltage region is surrounded by an isolation region having a low doping concentration. The use of a low-doped isolation region increases the size of an active region without reduction of a breakdown voltage.

摘要： A high voltage lateral Double diffused Metal Oxide Semiconductor (DMOS) transistor includes a plurality of well regions of a first conductivity type formed to be spaced out within a well region of a second conductivity type between a channel region of the first conductivity type and a drain region of the second conductivity type. Most current is carried through some portions of the well region of the second conductivity type in which the well regions of the first conductivity do not appear so that the current carrying performance of the device is improved. When a bias voltage is applied to the drain region, the well region of the second conductivity type is completely depleted at other portions where the well region of the second conductivity type and the well regions of the first conductivity type alternately appear so that the breakdown voltage of the device can be increased. In addition, since the well region of the second conductivity type can be easily depleted, not only the breakdown voltage can be increased, but also the impurity concentration of the well region of the second conductivity type can be increased. Accordingly, the on-resistance of the device can be decreased.
