In one embodiment, a method includes forming a base region for a transistor using a base mask and forming a contact region to the base region. The contact region is formed in an area that is at least partially outside of the base mask. The method then forms an emitter region in a diffused base region. The base region diffuses outwardly to be formed under the contact region.

Reduction of stored charge in the base region of a bipolar transistor to improve switching speed

An integrated device is provided which has a bipolar transistor as an output stage. The bipolar transistor is driven by a short channel metal oxide semiconductor field effect transistor. Such a device has a low on state voltage drop substantially irrespective of the potential supported by the device.
