New gallium-doped silicon 128 X 192 element arrays have been achieved at CEA-LETI- LIR (Infrared Laboratory) for imaging in the 8 - 14 micrometers spectral range. This program is in keeping with the previous detector developments for the ISOCAM camera (32 X 32 element arrays) and for ground-based observations (64 X 64 element arrays). The main features of the new detectors are: a pitch of 75 micrometers which leads to 10 X 15 mm2 chip dimensions, two selectable storage capacities (respectively 0.1 and 0.5 pF), a DVR readout circuit achieved in an NMOS silicon line with 1.5 micrometers design rules. The main electro-optical performances are the following: a peak responsivity of 4.0 A/W, a noise of 58 fArms over the 0.1 - 128 Hz spectral band which is very close to the BLIP noise, and a corresponding noise equivalent power of 1.4 10-14 W.
