Latest Patents

David Russell Hoag holds a patent for a heterojunction P-I-N diode and the method of making the same. This invention involves a heterojunction P-I-N diode switch that comprises a first layer of doped semiconductor material of a first doping type, a second layer of doped semiconductor material of a second doping type, and a substrate on which the first and second layers are disposed. An intrinsic layer of semiconductor material is placed between the first and second layers. The semiconductor material composition of at least one of the first and second layers is sufficiently different from that of the intrinsic layer, forming a heterojunction that creates an energy barrier. This design effectively reduces the series resistance within the I region of the P-I-N diode and minimizes insertion loss compared to homojunction P-I-N diodes.
