Latest Patents

Wei-Zen Chen holds a patent for a "Method for high transmittance attenuated phase-shifting mask fabrication." This innovative method involves forming a high transmittance attenuated phase-shifting mask through a series of precise steps. The process begins with a patterned shifter blank that includes a patterned shifter layer, which has a first variable transmittance and a first phase angle overlying a partially exposed transparent substrate. The substrate is then etched for a predetermined time to create trenches, which enhance the transmittance and phase angle. The shifter layer undergoes treatment with an aqueous solution to achieve the final desired transmittance and phase angle.
