Abstract: A method for inspecting a uniformity of CD (CD) of a photo mask pattern increases a production yield. The method obtains a CD by precisely measuring a photo mask by using, an electron microscope. Then, a measurement image having, a plurality of patterns formed in the photo mask is obtained by photographing the photo mask at a high speed through an optical microscope. A gray level based on the CD is calculated by capturing just a pattern area in the measurement image, and an estimated value and a correlation coefficient is obtained, when an open density of the measurement image is relatively low. Accordingly, a uniformity of CD can be confirmed more clearly in a measurement of high speed for a measurement image having a relatively low open density.

Abstract: A semiconductor device includes an active pattern including a channel region. The channel region is disposed between first and second source/drain patterns that are spaced apart from each other in a first direction. The channel region is configured to connect the first and second source/drain patterns to each other. A gate electrode is disposed on a bottom surface of the active pattern and is disposed between the first and second source/drain patterns. An upper interconnection line is disposed on a top surface of the active pattern opposite to the bottom surface of the active pattern and is connected to the first source/drain pattern.

Abstract: An object in a first image is segmented by obtaining the first image including the object; receiving a first input signal including first information about a first position in the first image; selecting at least one pixel included in the first image, based on the first information about the first position; generating a second image by dividing the first image into several areas, using the selected at least one pixel; and segmenting the object in the first image by using the first image and the second image.

Abstract: An adaptive encoding method includes splitting an input signal into a low-frequency band signal and a high-frequency band signal; performing forward adaptive linear prediction on the low-frequency band signal and thus filtering the low-frequency band signal; selectively performing backward adaptive linear prediction or long-term prediction on the filtered low-frequency band signal according to the analysis result of the low-frequency band signal; transforming the low-frequency band signal, on which backward adaptive linear prediction or long-term prediction has been performed, into a signal in a frequency domain and quantizing the signal; and encoding the high-frequency band signal using the low-frequency band signal, on which backward adaptive linear prediction or long-term prediction has been performed, or the quantized signal. Therefore, compression efficiency of both speech and music signals can be enhanced, and a robust compression method can be provided for various audio contents at a low bit rate.
