A semiconductor image sensor includes a bonding pad formed on a semiconductor substrate. An oxide layer is disposed over the semiconductor substrate to cover the bonding pad. A SOG is disposed on the oxide layer, a silicon-oxy-nitride layer is disposed on the SOG and a color filter is disposed thereon. By using the high transmittance of the SOG and the silicon-oxy-nitride layer, the blue light transmittance by the semiconductor image sensor is therefore enhanced.
