  We observed the giant HII region around the NGC 3603 YC with the 5 broad
bands (70, 160, 250, 350, 500 micron) of the SPIRE and PACS instruments,
on-board the Herschel Space Observatory. Together with what is currently known
of the stellar, atomic, molecular and warm dust components, this additional and
crucial information should allow us to better understand the details of the
star formation history in this region. The main objective of the investigation
is to study, at high spatial resolution, the distribution and main physical
characteristics of the cold dust. By reconstructing the temperature and density
maps, we found respectively a mean value of 36 K and Log(NH)=22.0+/-0.1
cm^(-2). We carried out a photometric analysis detecting 107 point-like
sources, mostly confined to the North and South of the cluster. By comparing
our data with SED models we found that 35 sources are well represented by YSOs
in early evolutionary phases, from Classes0 to ClassI. The Herschel detections
also provided far-IR counterparts for 4 H2O masers and 11 objects previously
known from mid-IR observations. The existence of so many embedded sources
confirms the hypothesis of an intense and ongoing star formation activity in
the region around NGC3603YC.
