| Outline of Final Research Achievements |
The target is development of an image sensor with the highest frame rate of 1 Gfps and the photon detection sensitivity. The achievements in the two-year project period are as follows: (1) Device structure: a 3D-stacked image sensor with a sensor chip and a driver chip both with innovative structures, (2) Simulation results on the highest frame rate: 6 Gfps (the frame interval of 160 ps) can be achieved, (3) Evaluation of the test devices: the driver chip achieved the frame interval of 1 ns (the frame rate of 1 Gfps); the sensor chip was damaged in the process, which is now under re-process. Since the sensor chip is made with a CCD structure, it can achieve several-photon detectable sensitivity with deep cooling.
