Patent number: 8898028Abstract: A device to inspect a non-pattern wafer includes a light source to emit light that reflected from a wafer. A judgment unit converts the detected light into a quantitative measured value to determine whether the wafer is faulty. The wafer comprises a first region and a second region. The detection unit sequentially detects lights reflected from the first and second regions of the wafer, and a judgment unit converts the lights reflected from the first and second regions of the wafer into first and second quantitative measured values, respectively. The second region of the wafer is determined to be faulty by comparing the second measured value with a first reference value, wherein the first reference value is calculated using an average value between the first and second measured values, and a characteristic value that indicates distribution of the first and second measured values.Type: GrantFiled: December 23, 2010Date of Patent: November 25, 2014Assignee: SAMSUNG Electronics Co., Ltd.Inventors: Byeong-Cheol Kim, Ho-Hyung Jung, Dong-Keun Shin
