Latest Patents

Among his most recent patents, Inoue introduced a semiconductor device and a method for manufacturing a semiconductor device. The manufacturing method aims to adjust the threshold to an appropriate value for optimal performance. The invented semiconductor device includes a semiconductor, a source or drain electrode connected to it, a first and second gate electrode sandwiching the semiconductor, an electron trap layer positioned between the first gate electrode and the semiconductor, and a gate insulating layer between the second gate electrode and the semiconductor. The method emphasizes trapping electrons in the electron trap layer by maintaining a higher potential at the first gate electrode than at the source or drain electrode for over one second, alongside heating. This innovation effectively increases the threshold and reduces Icut.

Furthermore, Inoue's method for manufacturing a semiconductor device aims to produce an oxide semiconductor film with stable electric characteristics and high reliability. The methodology involves forming a crystalline oxide semiconductor film by utilizing the difference in atomic weight of various atoms in the oxide semiconductor target. Specifically, zinc, having a lower atomic weight, is preferentially deposited, creating a seed crystal, while atoms like tin or indium with higher atomic weights are deposited on it, promoting crystal growth. This results in the formation of a single crystal oxide semiconductor film or a substantially single crystal oxide semiconductor film, enhancing the overall performance of the semiconductor devices.
