Patent number: 9544558Abstract: Provided is a phase shift amount measuring apparatus and method capable of measuring a phase shift amount and a transmittance of a phase shift mask in one measurement step by using a miniaturized monitor pattern. The phase shift amount and transmittance of the monitor pattern are simultaneously measured using a shearing interferometer. The phase shift amount is obtained from a phase difference of interference light between light passing through the monitor pattern and light passing through a non-pattern area. The transmittance of the monitor pattern is obtained using an amplitude of interference light between light passing through the monitor pattern and light passing through the non-pattern area and an amplitude of interference light between light beams passing through the non-pattern area. The use of common interference images in measuring the phase shift amount and transmittance enables measurement of both the phase shift amount and the transmittance in one measurement operation.Type: GrantFiled: December 2, 2014Date of Patent: January 10, 2017Assignee: Lasertec CorporationInventors: Koyo Tada, Hiroto Nozawa, Hideo Takizawa

The low order plates minimize the sensitivity of retardation across the aperture to non-collimated light. Materials are selected to ensure transmission of ultraviolet light. The optically isotropic end plates minimize coherence effects induced at the optical interfaces of the thin plates.Type: GrantFiled: August 22, 2014Date of Patent: December 13, 2016Assignee: KLA-Tencor CorporationInventors: Lawrence Rotter, Klaus Flock, Muzammil Arain, David Y.
