SEMICONDUCTOR DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18418368 titled 'SEMICONDUCTOR DEVICE
The semiconductor device described in the abstract consists of a semiconductor substrate with both a transistor portion and a diode portion. The transistor portion includes a main region separated from the diode portion by a boundary region, which contains a first boundary portion with an emitter region and a second boundary portion with an anode region and a contact region. The first boundary portion also features an injection suppression region to prevent the injection of carriers of the second conductivity type.
- The semiconductor device includes a transistor portion and a diode portion on a semiconductor substrate.
- The boundary region separates the transistor portion from the diode portion.
- The boundary region consists of a first boundary portion with an emitter region and a second boundary portion with an anode region and a contact region.
- An injection suppression region in the first boundary portion prevents the injection of carriers of the second conductivity type.
