B02

B02:Pioneering low temperature SOI infrared imaging toward understanding the evolution of the dusty universe.

Far-infrared imaging sensor is the key device to understand the birth and evolution of hidden star-formation in the dusty galaxies because far-infrared photon does not suffer from inter-stellar dust extinction compared with ultra-violet, optical and even X-ray photons.

Unfortunately, in the far-infrared wavelength, the technology for imaging sensor is not mature and the observations are limited in sensitivity and sky-coverage compared with the optical observation.

We will develop high-sensitivity large-format infrared sensors with these two breakthroughs, p+/-i infrared detectors (aka BIB detectors) fabricated by surface activated bonding (SAB) and molecular beam epitaxy (MBE), and cryogenic readout integrated circuit (ROIC) fabricated by fully-depleted silicon-on-insulator (FD-SOI) CMOS.
