Latest Patents

Kawasaki's latest patents include a semiconductor device and a method of manufacturing a semiconductor device. The first transistor in his design features a first gate insulating film, a first gate electrode, and a first sidewall. The second transistor is equipped with a second gate insulating film, a second gate electrode, and a second sidewall. A capacitive element is connected to one side of the source and drain regions of the second transistor. Notably, the first gate insulating film has the same thickness as that of the second gate insulating film, and the first gate electrode matches the thickness of the second gate electrode. Additionally, the width of the second sidewall is larger than that of the first sidewall.

Another significant patent is for a solid-state image sensor that has a planarized structure under a light shielding metal layer. In this design, shift register electrodes are formed in both the imaging area and the peripheral area using a single layer of conductive film. A thick insulating film is then deposited over these electrodes and planarized. The thick insulating film over the shift register electrodes in the peripheral area remains intact, while the film over the shift register electrodes is etched to fill gaps between them. This innovation allows for the formation of a light shielding metal layer without discontinuity, reducing parasitic capacitance and power consumption in the image sensor.
