  • Patent number: 12363459
    Abstract: A method is provided for forming a light-shielding layer to block irradiation of light onto a light-sensitive storage region. The light-sensitive storage region is formed in a semiconductor substrate to store electric charges. A storage gate feature is formed over the light-sensitive storage region, and includes a polysilicon gate electrode that is disposed over the light-sensitive storage region. A metal layer is formed over the storage gate feature. A silicidation process is performed to transform a part of the metal layer that is in contact with the polysilicon gate electrode into a silicide light-shielding layer. A thermal process is performed to induce lateral growth of the silicide light-shielding layer to make the silicide light-shielding layer extend to cover a lateral surface of the storage gate feature. A process temperature of the thermal process is higher than that of the silicidation process.
