  Within the framework of the HerM33es Key Project for Herschel and in
combination with multi-wavelength data, we study the Spectral Energy
Distribution (SED) of a set of HII regions in the Local Group Galaxy M33. Using
the Halpha emission, we perform a classification of a selected HII region
sample in terms of morphology, separating the objects in filled, mixed, shell
and clear shell objects. We obtain the SED for each HII region as well as a
representative SED for each class of objects. We also study the emission
distribution of each band within the regions. We find different trends in the
SEDs for each morphological type that are related to properties of the dust and
their associated stellar cluster. The emission distribution of each band within
the region is different for each morphological type of object.
