Latest Patents
One of his latest patents is a power semiconductor device and preparation method. This invention introduces a punch-through triode structure for electron extraction in a drift region. By doing so, it reduces the frontside hole injection efficiency and converts hole currents from emitters into electron drift currents without significantly increasing the on-state voltage drop. Additionally, the method allows for adjustments in the density and topography of a frontside trench, which changes the electron extraction and frontside hole injection efficiency. This advancement increases the design flexibility and dimensions of the device.
Another notable patent is the electron extraction type free-wheeling diode device and its preparation method. This invention provides multiple first structures to increase the density of electron extraction pathways on an N-type drift region. Each structure includes a lightly doped P-type base region and a heavily doped N-type emitter region. The ability to tune the barrier height of the punch-through NPN triode in a wide range has beneficial effects on the reverse recovery process.
