A semiconductor component and method of manufacture, including an
insulated gate bipolar transistor (IGBT) (100) including a semiconductor
substrate (110) having a first conductivity type and buried semiconductor
region (115) having a second conductivity type located above the
semiconductor substrate. The IGBT further includes a plurality of first
semiconductor regions (120) having the first conductivity type, a
plurality of second semiconductor regions (130) having the first
conductivity type, and a plurality of third semiconductor regions (140)
having the second conductivity type. A sinker region (142) having the
second conductivity type is disposed in a third semiconductor region and
a first semiconductor region during manufacture to define the plurality
of regions and tie the buried semiconductor region to the plurality of
third semiconductor regions. An emitter (150) having the first
conductivity type is disposed in one of the third semiconductor regions,
a collector (170) having the first conductivity type is disposed in the
other of the third semiconductor regions. A field poly plate (162) is
provided and tied to the collector (170). In a particular embodiment, the
plurality of third semiconductor regions and the buried semiconductor
region deplete the plurality of first semiconductor regions in response
to a reverse bias potential applied between the plurality of second
semiconductor regions and the plurality of third semiconductor regions.
