Latest Patents

One of his latest patents is titled "Method of fabricating semiconductor device with capacitor." This invention provides a fabrication method that prevents leakage current from increasing and dielectric breakdown resistance from decreasing during the chemical vapor deposition (CVD) or dry etching process for forming an insulating film to cover the capacitor. In this method, a lower electrode of a capacitor is formed on a first insulating film, which is typically placed on or over a semiconductor substrate. A dielectric film is then formed on the lower electrode, followed by an upper electrode that overlaps with the dielectric film. A second insulating film is created to cover the capacitor using a thermal CVD process in an atmosphere devoid of plasma, ensuring that hydrogen is not activated due to heat. The source material for this second insulating film is designed to prevent hydrogen generation during the thermal CVD process.

Another significant patent by Saito is for a "Semiconductor device with conductive plugs." This method involves manufacturing a semiconductor device that includes a CMOS section composed of both N-channel and P-channel MOS transistors, along with a memory section that features at least a transfer gate MOS transistor. A series of conductive plugs are formed to penetrate a laminate insulating film to connect with the MOS transistors. The laminate insulating film consists of a first and a second insulating film, while a capacitor section is constructed on top of this laminate. A third insulating film is then formed over both the laminate and the capacitor section, with a wiring pattern created to connect the conductive plugs.
