| 摘要 |
A semiconductor BiCMOS device and method of manufacturing suitable for attaining high packing density and thereby speeding up a switching operation, wherein the device is formed to have one of a source region or a drain region of an MOS transistor be immediately adjacent a base region of a bipolar transistor so as to be electrically connected. In this manner, an electrical terminal is eliminated, thereby permitting a higher packing density.
