Latest Patents

Aihara's latest patents include a method for manufacturing a tunnel junction layer. This innovative method utilizes organic vapor phase deposition and involves a series of processes to create a compound semiconductor layer. The first process supplies a first material gas containing a group III element, a second material gas containing a group V element, and a third material gas containing a dopant of a first conductivity type. The second process halts the supply of the first three gases and introduces a fourth material gas containing a dopant of a second conductivity type. Finally, the third process continues to supply the fourth gas while adding a fifth material gas containing a group III element and a sixth material gas containing a group V element.

Another notable patent is related to a light-emitting diode and the method for manufacturing the tunnel junction layer. This invention includes a light-emitting element layer composed of an n-type contact layer, a first light-emitting layer, a tunnel junction layer, a second light-emitting layer, and a p-type contact layer, all laminated in sequence. The first and second light-emitting layers emit light of the same wavelength, while the tunnel junction layer consists of a p-type tunnel layer made of AlGaAs and an n-type tunnel layer made of GaInP.
