Abstract:
An inspection method includes photographing a measurement target to acquire image data for each pixel of the measurement target, acquiring height data for each pixel of the measurement target, acquiring visibility data for each pixel of the measurement target, multiplying the acquired image data by at least one of the height data and the visibility data for each pixel to produce a result value, and setting a terminal area by using the produced result value. Thus, the terminal area may be accurately determined.
Abstract:
In a method of discharging bit-lines for a non-volatile semiconductor memory device performing a read-while-write operation. The method include discharging a global write bit-line to a ground voltage based on a write command within a first period. the method also includes maintaining the discharged voltage of the global write bit-line in the ground voltage during a second period.
Abstract:
An additive composition for a slurry contains a first salt of polymeric acid including a first polymeric acid having a first weight average molecular weight and a first base material, and a second salt of polymeric acid including a second polymeric acid having a second weight average molecular weight and a second base material. A slurry composition is prepared by mixing the additive composition, a polishing particle composition, and water. When implementing a chemical mechanical polishing using the slurry composition, a favorable polishing selectivity is realized.
