The CCD in almost all cameras is a Sony one, at least in the digicam area 
The surronding electronics usually not, and because that different camera brands have different image properties, but the CCD itself is the same in a S50, a Sony V1, a Canon G5, a Nikon 5400, etc, etc.
The DSLR area is a very different beast. All CMOS based Canon EOS have a Canon manufactured sensor, and the 1D I think is a Toshiba one (not sure here).
