Memory devices include a semiconductor substrate and a plurality of wordlines on the semiconductor substrate. A ground select line is on the semiconductor substrate on a first side of the wordlines and a string select line is on the semiconductor substrate on a second side of the wordlines. The wordlines extend between the ground select line and the string select line. First spacers are disposed between the wordlines, between the ground select line and an adjacent one of the wordlines and between the string select line and an adjacent one of the wordlines. Second spacers are disposed on sidewalls of the ground select line and the string select line displaced from the first spacers. The second spacers are a different material than the first spacers. The memory devices may be nonvolatile memory devices. Methods are also provided for forming the memory devices.

The present invention provides a 2 stage rotary compressor (100) including a hermetic container (101), a 2 stage compression assembly provided in the hermetic container, wherein a low pressure compression assembly (120), a middle plate (130) and a high pressure compression assembly (140) are successively stacked from any one of upper and lower portions, a first discharge port (124) for discharging middle pressure refrigerant compressed in the low pressure compression assembly (120) a second discharge port (162p) for discharging high pressure refrigerant compressed in the high pressure compression assembly (130) and a third discharge port (172p) positioned at any one of the upper and lower portions of the 2 stage compression assembly to discharge high pressure refrigerant compressed in the 2 stage compression assembly to the hermetic container (101), wherein an area of the third discharge port (172p) is larger than 0.5 times of an area of the first discharge port and smaller than 1.0 times thereof. As a volume flow of refrigerant compressed in the low pressure compression assembly (120) determines a volume flow of refrigerant compressed in the entire 2 stage compression assembly, a size of the third discharge port discharging refrigerant compressed in the 2 stage compression assembly is preferably optimized at a ratio with respect to a size of the first discharge port (127). Therefore, the size of the third discharge port (172p) can be optimized to suppress noise of the compressor.

In a NAND type nonvolatile memory device, a first insulating layer covers a common drain region formed in a string active region and a peripheral active region. A second insulating layer covers the first insulating layer. A bit line plug penetrates the first and second insulating layers and is connected to the common drain region. A peripheral lower plug penetrates the first insulating layer and is connected to the peripheral active region. A peripheral upper plug penetrates the second insulating layer and is stacked on the peripheral lower plug.

Provided are an apparatus and a method for measuring a three dimensional shape with improved accuracy. The apparatus includes a stage, at least one lighting unit, a plurality of image pickup units and a control unit. The stage supports an object to be measured. The lighting unit includes a light source and a grid, and radiates grid-patterned light to the object to be measured. The image pickup units capture, in different directions, grid images reflected from the object to be measured. The control unit calculates a three dimensional shape of the object from the grid images captured by the image pickup units. The present invention has advantages in capturing grid images through a main image pickup portion and sub-image pickup portions, enabling the measurement of the three dimensional shape of the object in a rapid and accurate manner.
