  • Publication number: 20190315113
    Abstract: A method includes cutting a glass laminate having a glass sheet laminated to a non glass substrate along a cutting path to form a glass laminate segment. Prior to cutting, a relief channel is formed in the glass laminate and comprises a first segment aligned with a final segment of the cutting path and a second segment extending away from the final segment of the cutting path. Another method includes forming a cutting channel in a glass laminate to define first and second regions of the glass laminate coupled by a web portion with a thickness of at least about 10% of a glass laminate thickness. The cutting channel is expanded to form an expanded cutting channel and a reduced web portion with a thickness of at least about 0.1% of the glass laminate thickness. The reduced web portion is severed to form a glass laminate segment.

  • Patent number: 8898028
    Abstract: 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.
