  A new type of bolometer arrays sensitive in the Far Infrared and
Submillimeter range has been developped and manufactured by CEA/LETI/SLIR and
will be integrated in the PACS instrument onboard the Herschel Space
Observatory (launch date 2008). The main innovations are their collective
manufacturing technique (production of 3-side buttable 16x16 arrays) and their
high mapping efficiency (large format detector and instantaneous Nyquist
sampling). Their measured NEP is 2x10^-16 W/Hz^-0.5 and their thermometric
passband about 4-5 Hz. In this paper we describe CEA bolometers and present the
results obtained during the last test campaign.
