    摘要: Semiconductor devices and methods of fabrication are provided. The semiconductor device includes a Charge Injection Controlled (CIC) Fast Recovery Diode (FRD) to control charge injection by lowering carrier storage. The device can have a first conductivity type semiconductor substrate, and a drift region that includes a doped buffer region, a doped middle region and a doped field stop region or carrier storage region. The device can also include a second conductivity type shield region including a deep junction encircling (or substantially laterally beneath) the buffer region and a second conductivity type shallow junction anode region in electrical contact with a second conductivity type anode electrode. The deep junction can have a range of doping concentrations surrounding the buffer regions to deplete buffer charge laterally as well as vertically to prevent premature device breakdown. The first conductivity type may be N type and the second conductivity type may be P type.
