With a total of three patents to his name, Iida has made significant advancements in the field, particularly in enhancing the performance and reliability of semiconductor devices.
Latest Patents
Iida's latest patents include a method of manufacturing a semiconductor device with a capacitor and transistor. This invention aims to prevent dielectric breakdown of a capacitor in a semiconductor device that incorporates both a capacitor and a MOS transistor on the same substrate. The process involves forming a SiO film as a gate insulation film on a P-type semiconductor substrate. A photoresist layer is selectively applied in the MOS transistor formation region, allowing for precise etching that protects the edges of trench isolation films adjacent to the capacitor formation region. This careful approach ensures that the remaining SiO film serves effectively as a capacitor insulation film.
Another significant patent by Iida is a semiconductor device manufacturing method that allows for the easy formation of a memory transistor and a high breakdown voltage MOS transistor on the same substrate without altering the operational characteristics of the memory transistor. This method separates the processes of forming the tunnel insulation film of the memory transistor and the gate insulation film of the MOS transistor, enhancing efficiency and performance.
