Latest Patents

Yuhji Ishida holds a patent for a molecular beam epitaxy apparatus. This apparatus comprises a growth chamber equipped with a holder support frame, which is connected via a first gate valve to a preparation chamber. The preparation chamber is further linked to a loading chamber through a second gate valve. A first transfer tray in the loading chamber receives a set of substrates from outside and advances into the preparation chamber. A second transfer tray supports a substrate holder in the preparation chamber, allowing the set of substrates to be transferred from the first tray onto the holder with the aid of a substrate transfer assembly. The second tray is then advanced into the growth chamber to transfer the loaded holder onto the holder support frame. This innovative design streamlines the substrate transfer process, making it more efficient.
