Title: Innovations of Junji Komeno
Introduction
Junji Komeno is a notable inventor based in Fujisawa, Japan. He has made significant contributions to the field of semiconductor technology, holding a total of 3 patents. His work focuses on enhancing the performance and efficiency of photodetectors and related apparatus.
Latest Patents
One of Komeno's latest patents involves the development of a semiconductor photodetector. This device includes a PIN photodiode and an avalanche photodiode, featuring an InP substrate, a first InP layer, a GaInAs or GaInAsP light absorbing layer, and a second InP layer. The layers are successively grown using a vapor phase epitaxial process, ensuring that the lattice constant of the GaInAs (GaInAsP) layer is larger than that of the InP layer at room temperature. This innovation results in a photodetector with a low dark current.
Another significant patent pertains to an apparatus for metal organic chemical vapor deposition (MOCVD) for growing semiconductors. This apparatus includes a transfer chamber positioned between the MOCVD reaction chamber and a load lock chamber. The design prevents foreign gases from entering the reaction chamber, which could oxidize metals used in MOCVD. The load lock chamber can be evacuated or filled with an inert gas, facilitating the safe transfer of semiconductor wafers. The transfer chamber is equipped with a gas inlet and outlet for continuous circulation of inert gas, ensuring a contamination-free environment for the wafers.
