| Outline of Final Research Achievements |
We have successfully developed a large format and low noise near infrared image sensor manufactured by a domestic company, which is required to build a near infrared wide field mosaic camera to study first stars and galaxies.
Although the readout noise of the sensor developed before with the same pixel size (15um) as the one of optical CCD sensors was higher than our requirement, we achieved the readout noise of 5e- this time, which was the goal of our development. Since we removed the image latency problem, the dark current less than 0.1e-/s/pix was achieved with also the large format sensor. The sensor assembled on a newly developed 3-side buttable package enables us to build the near infrared wide field mosaic camera in future.
