  • Method of depositing a material providing a specified attenuation and phase shift
    Publication number: 20060099519
    Abstract: The invention allows for the control of the attenuation and the phase of light transmitted through a deposited material. The invention is particularly applicable to the repair of attenuated phase shift photomasks. The transmission and the phase of the repaired area can be controlled. In a preferred embodiment, the phase of light transmitted through the repaired area is controlled by controlling the thickness of a deposited material, and the transmissivity of the repaired area is controlled by controlling the introduction of a contaminant into the repair area.
