Disclosed is a substrate alignment apparatus capable of performing coarse and fine alignments of a substrate in a progressing route to remove or reduce an alignment error between the substrate and a pattern roll. The coarse alignment may be performed by moving a frame using a stage when the alignment error is relatively large, and the fine alignment may be performed by moving subsidiary rollers of a roller unit relative to a main roller of a roller unit when the alignment error is relatively small. An example substrate alignment apparatus may include a frame and a roller unit rotatably fixed to the frame to support a substrate, wherein the roller unit includes a main roller, and at least one subsidiary roller fixed to the main roller such that the at least one subsidiary roller can move relative to the main roller to align the substrate.

A semiconductor memory device includes a semiconductor substrate in which a cell region and a core and peripheral region are defined. The device further comprises isolation layers formed in the semiconductor substrate to define active regions, a first gate electrode structure formed in the cell region and a second gate electrode structure formed in the core and peripheral region. Source and drain regions formed in the active regions on respective sides of each of the gate electrode structures and self-aligned contact pads are formed in the cell region in contact with the source and drain regions. An insulating interlayer is formed on the semiconductor substrate between the self-aligned contact pads, and etch stoppers are formed on the insulating interlayer between the self-aligned contact pads in the cell region.

摘要:
A first interlayer dielectric is formed on a semiconductor substrate. A contact pad is formed to contact the substrate through the first interlayer dielectric. A bitline is formed on the first interlayer dielectric not to contact the contact pad. A second interlayer dielectric is formed and planarized to expose the top of the bitline. A protective layer is formed an entire surface of the resultant structure. A sacrificial layer is formed on the protective layer. The sacrificial layer, the protective layer, and the second interlayer dielectric are patterned between two adjacent bitlines to form a bottom electrode contact hole exposing the contact pad. A conductive layer is formed and planarized to form a bottom electrode contact plug filling the bottom electrode contact hole.

摘要:
A high-precision displacement measurement device and linear or rotational displacement measurement method using a unit displacement sensor based on a confocal theory. This device is simpler in construction, lower in cost and superior in resolution to other displacement measurement devices, and is capable of measuring a much wider area than other measurement equipment. The present device is adapted to project a spot of light from a light source on an object whose displacement is to be measured and measure a relative displacement of the object from a displacement of the projected light spot. To this end, the unit displacement sensor includes a transmission lens for transmitting a divergent beam of light emitted from the light source through a slit or pinhole with a certain size, a collimating lens for collimating the light beam transmitted through the slit or pinhole, an object lens arranged between the collimating lens and the object, a beam splitter for splitting a beam of light, reflected from the object to the transmission lens, according to a wavelength, and a photodetector for detecting a light intensity of the light beam split by the beam splitter. A piezoelectric actuator is provided to finely move the unit displacement sensor so as to always maintain optical signals detected by the photodetector at the maximum intensity.
