A clear and comprehensive picture describing the physical processes which regulate the stellar mass assembly is still missing in galaxy formation scenario. I will present a measurement of the galaxy stellar mass function and stellar mass density from z=0.2 out to z=6. Our study relies on deep near-infrared imaging over wide fields: the WIRCAM/CFHT coverage of the 20 sq-deg VIPERS fields combined with the new IRAC/Spitzer coverage (the SPLASH survey) of the 2 sq-deg COSMOS field. Our analysis is based on photometric redshifts of 1,5 million of galaxies reaching a precision around 4% at 4
